Abstract

PURPOSE: To realize safe operation with variation in current reduced by canceling a surge voltage component in commutation of an inverter by providing a half-wave rectifying amplifier.
CONSTITUTION: Amplifier 12 is provided which performs half-wave rectification of a deviation component between voltage command signal ER and output voltage EF of rectifier 7. Its output signal EVF is applied across voltage regulator 8, which has resistance values R1, R2 and R4 selected with R1=R4=0.9R2 to obtain ER=EFDC/0.9 (EPDC is the direct-current component of voltage feedback signal EF.). Here, the figure shows equivalent feedback signal EFS found by deviation between EF and EVF and a surge voltage component is reduced by EP-ER.
