Title:
OPERATING DEVICE WITH STAGGERED PROTECTION CIRCUITS AGAINST OVERVOLTAGE AND OVERCURRENT AND ANTENNA FOR DRIVING INTELLIGENT LAMPS AND LIGHTING APPLIANCES
Document Type and Number:
WIPO Patent Application WO/2018/065120
Kind Code:
A3
Abstract:
In order to achieve a universal, flexible and highly integrated operating device for driving various lamps, ensuring the protection of the entire operating device and of the appliances connected thereto by means of staggered protective measures at both the input and the output, starting from the preamble of claim 1, a first branch for connecting a lamp to a first of the interface circuits (SS1) and a second branch for connecting at least one communication module to a second of the interface circuits (SS2) are connected to the coarse protection circuit (G) which short-circuits an overvoltage of the mains voltage occurring at the input of the operating device. In the first branch, a line filter (NF) is connected to the coarse protection circuit (G) and a clamp circuit (K) consisting of the fine protection circuit (F) and of a first energy absorber (E1) is connected to the line filter (NF). When the residual pulse voltage is too high, the fine protection circuit (F) activates the first energy absorber (E1), the overvoltage pulse is short-circuited and the short-circuit is deactivated again when the mains voltage reaches the next zero crossing. A second energy absorber (E2) which, when it is switched on, limits the current with the aid of a temperature-dependent resistor (NTC), is connected to the first energy absorber (E1). Moreover, the first interface circuit (SS1) comprises a protection circuit (ÜS) against overvoltage and overcurrent, and an intermediate protection circuit (M) consisting of a transmitter (Ü) and of a first fine protection circuit (F1) is connected to the coarse protection circuit (G) in the second branch. A filter (FK) for separating communication signals fed in parallel into the power supply grid is connected to the first fine protection circuit (F) and a second fine protection circuit (F2) is connected to this filter (FK). In order to protect the second interface circuit (SS2) of the operating device from overvoltage and overcurrent coming from the communication module and acting upon the operating device, the second interface circuit (SS2) comprises a protection circuit (ÜS) against overvoltage and overcurrent. The invention is used in the field of protection systems against overvoltage.
