A prepositioned highly precision voltage regulator of AC regulated power supply based on single-chip micro-computer
This paper presents a novel prepositioned highly precision voltage regulator method based on single-chip micro-computer, uses a timing AC Servo Power Supply to make use of servo motor controlling Autotransformer, explains the working principle of the circuit, gives flowchart software,hardware block diagram and circuit schematic diagram. The realization of intelligent prepositioned highly precision voltage regulator and timing AC servo power Supply based on single-chip micro-computer, which has the feather of high accuracy and pre-set adjustable AC voltage. The function of which is highly power supply efficiency, stepless auto voltage, widely regulator range,small waveform distortion, timing regulator output, over voltage protection, under voltage protection, over current Protection, self protection circuit and smart alarm clock.
