Abstract

The invention provides a rectifier system based on multi-winding input. According to the rectifier system based on multi-winding input, the advantages of a phase-shifting transformer are fully utilized, a multi-winding input mode is adopted, on the premise that the direct-current output performance index of the rectifier is met, the circuit topological structure of the rectifier is simplified, thecost of the rectifier system is reduced, and the efficiency of the rectifier system is improved; and meanwhile, the reliability of the rectifier system is also improved.

Description

technical field [0001] The invention relates to the field of power supply and distribution of power electronic converter devices, in particular to a rectifier system based on multi-winding input. Background technique [0002] Currently, power electronic rectifiers are used in the field of power supply and distribution in power systems. The input of rectifiers is mostly three-phase AC mains. In order to meet the requirements of AC input harmonics and output DC performance indicators, the current circuit topology of rectifiers is widely used. Architecture, the front stage is generally a power factor correction circuit, and the rear stage is an isolated rectification circuit. This circuit topology can meet the requirements of AC input harmonics, and at the same time, it can ensure that the indicators of the output DC are optimal. However, this topology has a cost The disadvantages of high and low efficiency. At present, with the development of the new energy field, the demand ...
