DRIVE CIRCUIT FOR SWITCH

DRIVE CIRCUIT FOR SWITCH

A drive circuit drives a switch configuring a power converter. The drive circuit divides an inter-terminal voltage of a switch. The drive circuit includes a differential circuit having first and second input terminals to which the divided inter-terminal voltages are inputted. The differential circui...

description A drive circuit drives a switch configuring a power converter. The drive circuit divides an inter-terminal voltage of a switch. The drive circuit includes a differential circuit having first and second input terminals to which the divided inter-terminal voltages are inputted. The differential circuit outputs an analog voltage based on a voltage difference between the input terminals. The differential circuit executes reset of the output voltage, and with the voltage difference when reset is canceled after reset is executed as a reference voltage, outputs an analog voltage in which an amount of change from the reference voltage is multiplied by an amplification factor. The drive circuit outputs a binary signal based on comparison results between a threshold and the analog voltage outputted from the differential circuit, and sets a transfer rate of a gate charge of the switch when a driving state is switched, based on the output signal thereof.
