Resum
This paper describes an electronic device that enables AC contactors to ride through power quality dsturbances. The proposed device is connected to the contactor coil and consists of a power conversion excitation and hold-in crcuit, a control circuit, an immunity circuit and a shutdown circuit. It does not disturb contactor operation, is easy to use nd can be built from cheap, commercially available components. Experimental tests have demonstrated the efectiveness of the proposed electronic devi...
