Abstract
A rectifier circuit including a switch element, controls connection and disconnection of an AC input voltage using the switch element to generate an output voltage. The switch element includes an n-channel MOS transistor. The rectifier circuit further includes a booster circuit and a control signal generation unit, and establishes connection to the switch element at a peak portion of the input voltage. The booster circuit is configured to generate and apply a gate control signal including a voltage higher than a threshold voltage of the n-channel MOS transistor to a gate of the n-channel MOS transistor. The control signal generation unit is configured to generate and output a control signal for controlling connection and disconnection of the n-channel MOS transistor to the booster circuit.
