Abstract (en)
[origin: US2019035584A1] A controllable electric current switchgear includes a bistable relay including separable electrical contacts and an excitation coil for switching the contacts between open and closed states when the coil receives an amount of energy that is higher than a predefined excitation energy threshold with an electrical power that is higher than a predefined power threshold; and a control circuit including a power stage and a logic stage for triggering the switching of the relay. The power stage includes a power converter, a first set of capacitors connected at the input of the converter and a second set of capacitors connected at the output of the converter, the nominal power of the converter being strictly lower than the power threshold, the sets of capacitors being capable of storing an amount of energy that is higher than or equal to 50% of the excitation energy threshold.
