Abstract
A gate drive circuit in an aspect of the present disclosure includes a modulated signal generation circuit that generates a first modulated signal, a first isolator that isolatedly transmits the first modulated signal, and a first rectifier circuit that generates a first output signal by rectifying the first modulated signal. The first modulated signal includes a first amplitude, a second amplitude larger than the first amplitude, and a third amplitude larger than the second amplitude. The first output signal includes a first output voltage value according to the first amplitude, a second output voltage value according to the second amplitude, and a third output voltage value according to the third amplitude.
