Modular series combined converter based on multi-phase permanent magnet generator

Abstract

The invention relates to a modular series combined converter based on a multi-phase permanent magnet generator. The modular series combined converter comprises n three-phase windings, the alternatingcurrent output by any one of the three-phase windings passes through precharge modules, filters, standard rectifier modules and braking modules of the converter in order and then outputs a direct current, and the direct current is connected with a DC distribution board or a DC circuit breaker; the n groups of the same precharge modules, the n groups of the same filters, the n groups of the same standard rectifier modules and the n groups of the braking modules are respectively arranged in the independent 4 cabinets, and each cabinet comprises a set of cooling system. The modular series combined converter is high in integration modularization degree, high in output voltage and small in engineering implementation difficulty, is used for achieving the controllable electric energy conversion between the AC output of the multi-phase high-speed permanent magnet generator directly connected with a prime mover and a medium voltage DC grid.
