    Abstract: The invention relates to a circuit arrangement to provide electronic tripping devices with electricity from a current transformer (SW). A switched-mode power supply unit (SNT), especially a reactance step up transformer(DR) with a pulse-width voltage control, is located downstream from the charging capacitor (CL). When set value (UA) is reached for output current at an output capacitor (CA) only a very high pulse duty factor is provided. Maximum power point control is provided in the initial phase of charging. Such circuit arrangements are used to provide an electricity supply for low and medium voltage overload tripping devices.

    Abstract: For use in a trip unit, a switched current shunting arrangement in a circuit interruption tripping system couples the current transformers (A, B, C, G, F) to relatively low voltage and it accumulates a high level of energy quickly at power-up so that the tripping solenoid (128) can promptly be energized after the detection of a spurious fault condition. The arrangement regulates supply current from the current transformers to a trip voltage capacitor (78) and to a supply capacitor (20') at the input of a voltage regulation circuit. The current transformer charges the trip voltage capacitor to a first prescribed voltage level, and a current shunting circuit (142, 144) shunts current passing from the current transformer to the supply capacitor, such that during normal operation the supply capacitor is charged to a second prescribed voltage level, which is less than the first prescribed voltage level.
