Abstract

PURPOSE: To improve the efficiency of rectification, by supplying the gate of a field- effect transistor with a signal corresponding to the polarity of a rectified signal, from a gate signal generator which is controlled by the output of a rectified signal polarity detector.
CONSTITUTION: The polarity of the voltage of an AC power source 4 as a rectified signal source is detected by the polarity detector 2. A voltage corresponding to the polarity of the voltage of the AC power source is applied to the gate of the insulator- gate field-effect transistor 1 from the gate signal generator 3 which is controlled by the output of the polarity detector 2. If the MOSFET 1 is an N-channel one, the gate is set positive when the drain is positive and the source is negative. If the MOSFET 1 is a P-channel one, the gate is set negative when the drain is negative and the source is positive.
