バー回路。 In an inverter that drives an induction motor by inversely converting the DC obtained by forward converting an AC power source, there is a photocoupler consisting of two light receiving elements that are turned on and off by one light emitting element, and a light receiving element of one of the photocoupler. One transistor turns on when the element turns on, the other transistor turns off when the other light-receiving element turns on, and the one transistor turns on.
ON with N operation and OFF operation of the other transistor
An inverter driver circuit consists of a main circuit power transistor, and a circuit that applies a reverse bias to the power transistor, which is turned off when one transistor is turned off, and reverse biased when the other transistor is turned on.
