FIELD OF TECHNOLOGY

The present innovation generally relates to wireless energy transfer or wireless power transfer for circuit breaker apparatus, and in particular Electronic Circuit Breakers (ECB) which are designed to protect an electrical circuit from damage and monitor current usage.

BACKGROUND OF THE INNOVATION

Circuit breaker apparatuses provide protection in electrical systems by monitoring characteristics of the electrical power supplied to loads and interrupt the flow when fault conditions (e.g., arc faults, ground faults, unsafe current level) are detected. Some circuit breaker apparatuses additionally allow for remote control, such as the ability to open or close the circuit breaker's detachable contacts in response to an external control signal.

In Iraq, power generating companies sell electricity to each household based on the maximum current usage required. Unlike most countries, Iraqis use MCBs not only for protection in electrical systems, but also to limit their electricity usage. Common circuit breaker apparatus or MCBs usually needed to be reset manually after a trip occur. It will be wasting manpower and time consuming in locating the tripped circuit breaker apparatus if one is not familiar the whereabouts or the premises is very large which may impact the production line or one’s daily activity. Electronic Circuit Breaker (ECB) is improved version of MCB, tackling this challenge by resetting the circuit breaker apparatus automatically after a period of time set by the user, which is beneficial to Iraqi users as well as users from other countries.

The conventional way of powering up ECB is by using Live and Neutral wire. However, this system, raises the cost of additional wiring and circuit breaker panels size due to ECB size is doubled compare to MCB, as well as the time it takes to maintain them if sudden breakdown were to occur.

Therefore, a need exists for circuit breaker apparatuses that has less complexity and that require less external wiring at the circuit breaker panels for powering the circuit breaker apparatuses is desirable.

DETAILED DESCRIPTION OF THE INNOVATION

One embodiment of the innovation relates to a method and system configured to monitor and programme operation of a circuit breaker apparatus.

The present invention relates to a system configured to power up electronic circuit breaker apparatus wirelessly. Wireless energy transfer has the potential to transmit radio frequency (RF) energy over close distances.

The system comprises of two main parts, at least one energy transmitter (1 ) and at least one energy receiver electrical miniature circuit breaker (EMCB) or circuit breaker (3). The transmitter antenna (2) connected to the energy transmitter (1 ) continuously radiates RF energy (5) to its surrounding, which powers up the circuit breaker (3) apparatus through the receiver antenna (4).

As illustrated in Figure 4, the system of the circuit breaker apparatus comprising, an input power or a load current connection and an output power or a line current connections at the circuit breaker apparatus, wherein the line current from the circuit breaker apparatus for powering at least one powered device, or sockets for appliances such as lighting, fan, and such.

Further the circuit breaker apparatus has a LED for status indication of the circuit breaker apparatus, buttons for setting up or adjusting settings of the circuit breaker apparatus, and seven segment display to display the measurement or indicate status of settings.

Figure 5 illustrates the block diagram concept of energy transmitter and energy receiver. The transmitter drives an external antenna through antenna driver output pins to generate the RF field. The drivers are designed to directly drive antenna(s) integrated on the PCB as well as antennas connected with 50 Q cables. In this design, these drivers are differentially driving the external antenna.

When power on, the Bluetooth MCU (41 b) initiates the transmitter IC (42b). Thereafter, the pins of the antenna driver output an unmodulated carrier signal at 13.56MHz. These unmodulated carrier signal first passes through the EMI filter and matching circuit, before reaching the antenna. The EMI filter will then filter out high harmonics, extracting and removing electromagnetic noise from noisy components whereas the matching circuit matches the source impedance to the load impedance. Thus, the transmitter antenna (42c) receives maximum power of the signal with minimum reflection from the load. Finally, the transmitter antenna (42c) can radiate the signal, which is also known as RF energy across space. The transmitter antenna (42c) and receiver antenna (44c) are mutually coupled together. By means of a tuned receiver antenna, RF energy can be transferred from the transmitter antenna, using similar principle like a voltage transformer. RF energy exchange can be optimized when both the transmitter and receiver antennas are tuned to the same frequency, known as resonant frequency. Thus, allowing maximum power transfer between the antennas by reducing the signal reflection. The receiver antenna is connected to an internal rectifier packaged in the IC, where the RF energy undergoes full wave rectification. A portion of this energy is used to power up the receiver’s IC. While the remaining energy outputs to the output pin, which are then used to supply to other circuitry components (e.g., IC, relay, LED).

When power is sufficient, data exchange can be done between transmitter and receiver. To send command to the receiver, the transmitter first performs ASK modulation on the carrier. These modulated signals will be radiated across space and received by the receiver antenna (44c). The receiver consists of a demodulator capable of performing AM demodulation. Once the signal has been demodulated, the receiver is able to access and extract information within it.

At the end of the request, the transmitter keeps the unmodulated carrier signal to power the receiver, and allow it to generate an acknowledgement. When the receiver is ready to respond, it performs passive load modulation technique by changing its antenna impedance. Therefore, the receivers IC (44b) input impedance variation modulates the acknowledgement signal across the transmitter antenna. The transmitter receives the modulated signal and performs demodulation, thus retrieving the acknowledgement.

As illustrated in Figure 6, the method of operation of the system comprising steps of:

Transmitter control unit powers up energy transmitter circuit (51 ), in which energy transmitter circuit having Integrated Circuit (IC) connected, sets up Transmitter IC to perform wireless power transmission operation (52). • Thereafter, the T ransmitter IC Channeling power to antenna (53) and radiate RF energy (54), where at the same time, Receiver IC will be waiting (55’) for RF energy until its made available or received (55).

• Then, the Receiver antenna receive RF energy, power on (56) and setup the Receiver IC embedded or affixed onto the circuit breaker (57). The Transmitter IC then sends data for communication to the Receiver IC (58). The Receiver IC receives data (59) and process the data, perform embedded instructions (60) and transmit back acknowledgement for the transmitter IC (61 ). The Receiver IC also will check and wait for additional data from transmitter IC, if there is any.

• Otherwise, the Receiver IC transmit the acknowledgement to the transmitter I, where the transmitter IC receives data (62) to perform additional instructions and sends data to receiver IC if required (63).

Every component (e.g., MCU, relay, coil, LEDs) in the electronic circuit breaker apparatus are powered up by the converted RF energy without relying any power from live wires. The electronic circuit breaker apparatus collects current usage data periodically and determines whether it is overcurrent or short circuit. If it is, the relay will open its contact interrupting the current flow. After a period of time set by the user, the relay automatically resets itself, resuming current flow. Automatic reconnection eliminates the need for the user to manually reset the circuit breaker apparatus. A supercapacitor will also be mounted for temporary energy storage.

The design of the circuit breaker apparatus comprising, actuator lever used to automatically or manually trip and reset the circuit breaker apparatus. The position of the lever able indicate the status of the circuit breaker apparatus (On or Off/tripped). The lever can be remotely controlled by having controller unit or relay control coupled to the circuit breaker apparatus, in which the relay control able to turn on automatically without the need to manually switch it back on during current surge or turn on remotely via wireless connection to the circuit breaker apparatus. Further the circuit breaker apparatus has a LED for status indication of the circuit breaker apparatus and buttons for setting up or adjusting settings of the circuit breaker apparatus. The circuit breaker apparatus has capacitor or supercapacitor for charged up for storing power for use of the circuit breaker apparatus components. The live supply is not required to power up the circuit breaker apparatus, as the circuit breaker apparatus has a completely isolated power supply to power up the circuit breaker apparatus components. The Live wire or live supply will only pass through a coil allowing current detection and exist as line current or output current for powering at least one powered device. The Relay control enables electrical miniature circuit breaker (EMCB), Electronic Circuit Breakers (ECB) or circuit breaker apparatus to turn on automatically without the need to manually switch it back on during current surge or short circuit. The Bluetooth Low Energy (BLE) pairing between the circuit breaker apparatus and master controller or remote unit is done through using mobile application or buttons.
