Abstract
A first drive circuit Da includes a temperature information transmission unit that transmits a binary output signal changing between High and Low and an abnormality information transmission unit that transmits an output signal fixed to Low, and a second drive circuit Db includes the abnormality information transmission unit. A temperature information signal and an abnormality information signal from the first drive circuit Da are subjected to OR operation on the side nearer the first drive circuit Da than to a magnetic coupler Ma so the abnormality information signal takes precedence when the abnormality information signal represents an abnormality, or on the side nearer a control unit than to the insulation elements Da and Db so the output signal from the insulation element Db takes precedence when the abnormality information signal from the second drive circuit Da represents an abnormality, and then the logical sum is output to the control unit.
