Rectification system for permanent-magnet synchronous generator

The invention discloses a rectification system for a permanent-magnet synchronous generator. The rectification system comprises: a prime mover, a permanent-magnet synchronous generator connected to the prime mover; a rectifier connected to the permanent-magnet synchronous generator through a breaker; a shore power source connected to the rectifier through a connector; a field controller connected between the permanent-magnet synchronous generator and the rectifier, wherein the input of two types of power sources is enabled under control of the field controller by disconnecting the breaker or the connector. The invention provides a rectification system for a permanent-magnet synchronous generator that is applicable to vessels. Said rectification system enables an input mode of both the permanent-magnet synchronous generator and the shore power source which are AC power sources with different voltages and frequencies. Also, Said rectification system can perform automatic detection of the input voltage and frequency at the input of the rectifier in the system, thereby achieving desired outputs of DC voltage and current.
