Application of the Timer Resources of the Chip Microprocessor in Digital AC Voltagc regulator

The switching AC voltage regulator is divided into two regulating ways:phase-modulated voltage regulating and power-modulated voltage regulating.The paper presents a microcomputer phase modulation to control four-way digital AC voltage regulator.It uses minimus system layouts that can effectively achive pulse sequential management to the asynchronous voltage regulating of four-way voltage regulator by making rational use of the timer resources of the chip microcomputer.
