SINGLE-PHASE LOADED BRIDGE RECTIFIER

摘要

The invention relates to electrical engineering and can be used in power electronics. Its aim is to improve the quality of DC voltage in the output of loaded single-phase rectifier. Main single-phase loaded bridge rectifier is supplied from one half-winding of secondary center tap winding of transformer, but to the other half-winding there are connected the diodes-capacitors voltage doubler and auxiliary single-phase rectifier with capacitor at output, which represent a reference voltage. Positive pole output of the doubler is connected to collector of n-p-n transistor, its emitter is connected to positive output clamp of the main rectifier, a base of transistor is connected to positive output clamp of auxiliary rectifier, but negative poles of the main and reference rectifiers and voltage doubler output are consolidate as ground point.
