Abstract

Official abstract text for this publication.

An inverter device includes an inverter circuit, a control circuit, a first drive circuit, a second drive circuit, first and second photocouplers, and a signal switching part. The signal switching part directly transmits the first and second signals outputted from the first photocoupler and the second photocoupler to the corresponding first and second drive circuits respectively when at least one of the first and second signals is an OFF command.

First claim

Opening claim text (preview).

The invention claimed is: 1. An inverter device comprising: an inverter circuit which includes an upper-arm-use first switching element and a lower-arm-use second switching element; a control circuit which outputs a first signal which is an on or off (ON/OFF) command for the first switching element and a second signal which is an ON/OFF command for the second switching element respectively; a first drive circuit which performs ON/OFF driving of the first semiconductor switchin…
