IPC: H02M7/48
Filed: 1989-08-09
Abstract: PURPOSE:To detect a mean current which is supplied without using any current transformer by integrating a voltage developed across a resistance for instantaneous overcurrent detection in the inverter by an integration circuit and processing its value by a microcomputer. CONSTITUTION:The integration circuit 5 integrates the voltage developed across the resistance Rs for instantaneous current detection which is supplied to a power transistor PM in the inverter 1 and a voltage signal obtained by it is inputted to the port(ID) of the microcomputer 6.
