IPC: G01R19/00
Filed: 1987-10-22
Abstract: PURPOSE:To reduce heat generation by amplifying the primary-side current of a photocoupler by a transistor (TR) and then supplying the current. CONSTITUTION:Resistances 7 and input terminals of TRs 9 are connected in series between respective phases of the output of an inverter part 3 and the negative side of a converter part 1, output terminals of the TRs 9 and input terminals of photocouplers 6 are connected in series, and a power source is connected to input terminals of the photocouplers 6, thereby detecting the output voltage of a controller according to the outputs of the photocouplers 6. Here, the TRs 9 amplify current values so that the primary currents required to turn on the photocouplers 6 are supplied. Then the resistance values of the resistances 7 and 8 are so selected that when the potential at a point U is a DC voltage Vdc, the output currents of the TRs 9 turn on the photocouplers 6. At this time, currents supplied to the resistances 7 only have values obtained by dividing the primary currents required to turn on the photocouplers 6 by the amplification factor of the TRs 9, so the currents flowing through the resistances 7 are extremely small and the heat generation of the resistances 7 is therefore reduced.
