Abstract:

In order to improve reliability and stability of threephase rectifier circuit controlled by integrated shift trigger, a method of closed loop system is given by deduction and analysis of the circuit transfer function. Meanwhile, it proposes a method to realize the soft start of control circuit based on the analyzing the start process of rectifier circuit. Finally, the experimental testing results and corresponding analysis are given which provide a good reference for the practical engineering application of threephase rectifier circuit controlled by integrated phase shift trigger.

Key words:

phase shift trigger, threephase rectifier circuit, closed loop control, soft start
