MULTISHAFT POWER SUPPLY CIRCUIT OF TRANSISTOR INVERTER AND UNIT CIRCUIT THEREOF
Document Type and Number:
WIPO Patent Application WO/1998/048505
Kind Code:
A1
Abstract:
A multishaft power supply circuit of transistor inverters wherein the number of parts is small, the size is small, the manufacturing cost is low, and the development efficiency is improved. The circuit comprises: a high-frequency transformer (2) having a primary winding connected to a dc output power supply and a plurality of secondary windings; a plurality of rectifying/smoothing circuits (4) for rectifying and smoothing the output voltages of the secondary windings of the transformer (2); a dc output power supply (1); a switching circuit (3) for applying a high-frequency generated from the dc output voltage to the primary winding of the transformer (2); a plurality of drive power supplies composed of the outputs of the circuits (4); and a stabilizing circuit (5) for controlling the circuit (3) by using a common control power supply V�cc? that is connected to at least one of the outputs of the circuits (4).
