Abstract
A power device control circuit enters a gate driving signal into a gate terminal of a power device. The power device control circuit includes: a control signal input circuit that receives a power device control signal for control of the power device; a driving system control circuit connected to the control signal input circuit; a driving circuit with a plurality of driving systems, the driving circuit driving the power device in response to a driving circuit control signal received from the driving system control circuit; and a timer circuit that makes switching between the driving systems in response to the driving circuit control signal after elapse of a given period of time from receipt of a predetermined signal, specifically the power device control signal, thereby changing the driving power of the driving system control circuit to drive the power device.
