A rectifying circuit having rectifying elements in the form of FETs (Field Effect Transistors) and applicable to a switching regulator or similar device. The rectifying circuit has a gate discharging circuit which half-wave rectifies the drive voltages for the FETs and discharges charges stored in the gate capacitance of each FET. The circuit reduces the drive losses of the FETs to a considerable degree.
