摘要： An output circuit for a PWM inverter is provided which has an N-type first power device and a P-type second power device. Gates of the first and second power devices are connected to each other. Also, emitters of the first and second power devices are connected to each other. An input electrode control circuit controls the voltage applied to the common gates with respect to the common emitters. The voltage may be a positive or negative value, or zero. The input electrode control circuit controls the conduction states of the two power devices based upon the states of input light emitting devices associated with a first and second photocoupler (current generator). When both of the photocouplers are not lit, no current is generated and the conduction states of the power devices are instantaneously interrupted.

摘要： A PWM inverter output circuit enabling circuit integration, having a fast response characteristic, and unaffected by dv/dt transients is provided. A predrive circuit 17 drives a power circuit 11 comprising first and second power elements P1 and P2 by controlling the gate and source potential of the power elements P1 and P2 based on a stored control state. The control state is detected from a logic signal output from an input signal processor 13, which converts a command signal instructing turning on and off the power elements P1 and P2 to predetermined logic signals. Operating power is drawn from a main dc power source V1, a control power source V2, and a power supply capacitor C1 that is charged using an output voltage from the control power source V2. The gates and sources of the power elements P1 and P2 are connected together.
