Controller for inverter device

Abstract

Abstract PURPOSE:To sufficiently use only one pulse width modulation controller by applying a control signal from a pulse width modulation control circuit to the first inverter and applying a control signal from the control circuit to the second inverter at the low output voltage time. CONSTITUTION:A control signal P1 is applied to the transistors Ua-Za of the arms of the first inverter 101a through a pulse amplifier 113a at one pulse mode time, and a control signal P3 outputted from a control signal generator 201 is applied to the transistors Ub-Zb of the arms of the second inverter 101b through a pulse amplifier 113b. The control signal P1 outputted from a pulse width modulation controller 112a is applied to the both first inverter 101a and the second inverter 101b at the pulse width control time, and the inverters 101a, 101b are controlled in the pulse width by the fixed phase difference.
