THE SYNCHRONOUS RECTIFIER TYPE ALL WAVE RECTIFIER USING THE FIELD EFFECT TRANSISTOR

摘要

PURPOSE: A synchronous rectification type full wave rectifier circuit using a field effect transistor is provided to reduce the energy loss by minimizing the efficiency of reduction. CONSTITUTION: A first rectifier (110) includes one capacitor and one diode. The first rectifier is conducted when the voltage of AC1 is over the voltage of AC2. A second rectifier (120) is conducted when the voltage of the AC2 is over the voltage of the AC1. A third rectifier (130) is conducted when the voltage of the AC2 is over the voltage of the AC1. A fourth rectifier (140) is conducted when the voltage of the AC1 is over the voltage of the AC2.
