A Novel Precise AC Stabilized Power Supply

In this paper, a novel precise A. C. stabilized power supply is presented and its operating principle is analysed. In this power supply, the output voltage is the sum of input voltage and compensating voltage which is controlled by using A. C. chopper with double frequency mode. The feedback regulator is a pulse sample noerror adjustment system. Analysis and experiments show this stabilized power supply has a series of advantages.
