Abstract

In a signal transmission circuit including a drive circuit and a control apparatus which are insulated from each other and between which a signal indicative of predetermined information is transmitted via a magnetic coupler, the drive circuit includes a temperature information transmission unit transmitting a first signal indicative of temperature information based on the number of pulses consecutively output with a predetermined period and each having a first waveform with a duty cycle of less than 100% with respect to the period and an abnormality information transmission unit transmitting a second signal indicative of abnormality information based on a pulse having a longer wavelength than the first waveform. The temperature information transmission unit transmits the first signal to the control apparatus and the abnormality information transmission unit transmits the second signal to the control apparatus, via the magnetic coupler common to two information transmission units.
