Abstract
The number of ICs used for a power converter is reduced. The power converter includes n power transistors each having an emitter terminal or a source terminal connected to a common line, and driver ICs. Each of the driver ICs includes n pre-drivers that drive the respective n power transistors, and a receiver circuit that is integrated monolithically with the n pre-drivers. The receiver circuit is coupled with a transmitter circuit by AC coupling, and outputs a control signal that controls the n pre-drivers in response to a signal received from the transmitter circuit.
