摘要
A non-isolated symmetric self-coupling 18-pulse rectifier power supply system comprises a phase-shifting autotransformer, three circuits of output devices, a time sequence controller and a power output end. The phase-shifting autotransformer is provided with three groups of output ends and one group of input ends, and the output device in each circuit comprises a zero-sequence suppression reversing inductor, a three-phase uncontrolled rectifier bridge and a bidirectional switch BUCK converter, which are connected to each other in turn. The time sequence controller is provided with three groups of control ends which are respectively connected to the control end of the bidirectional switch BUCK converter in each circuit. The output end of the bidirectional switch buck converter in each circuit is connected to the power output end.
