Abstract

See full text

An output node at a plus side of a diode bridge (DB2) is connected to a drain of a transistor (Q1), and a source of the transistor (Q1) is connected to an output node at a minus side the diode bridge (DB2). One end of a resister (R1) is connected to the drain of the transistor (Q1), and the other end of the resister (R1) is connected to a gate of the transistor (Q1). One end of a resister (R2) is connected to the gate of the transistor (Q1), and the other end of the resister (R2) is connected to the source of the transistor (Q1). A capacitor (C1) is connected in parallel to the resister (R2).
