Title:
DC-AC INVERTER PROTECTION CIRCUIT FOR LITHIUM BATTERY AND ENERGY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/238306
Kind Code:
A1
Abstract:
The present application discloses a DC-AC inverter protection circuit for a lithium battery and an energy storage device. The inverter protection circuit comprises a switch control circuit, a pulse width modulation integrated circuit, a compensation resistor, a compensation capacitor, a coupler receiving end, a bypass capacitor, a timing resistor, a timing capacitor and a pull-up resistor. The pulse width modulation integrated circuit comprises a power supply pin, a first output pin, a second output pin, a non-inverting input pin, an inverting input pin, a compensation pin, a timing resistor pin, a timing capacitor pin, a reference voltage pin, an oscillator, an error amplifier and a comparator. The energy storage device comprises the inverter protection circuit. The present application reduces the peak-to-peak current of a lithium battery, so that the lithium battery is able to work within a rated charging and discharging rate.
