1. A generator system based on a high-frequency isolated matrix converter, comprising:
a permanent magnet synchronous generator;
a high-frequency matrix converter, wherein an output port of the permanent magnet synchronous generator is connected to a three-phase input of the high-frequency matrix converter;
a center-tapped high-frequency transformer, wherein positive and negative output poles of the high-frequency matrix converter are connected to the primary side of the center-tapped high-frequency transformer, and a middle pole of the high-frequency matrix converter is connected to a center tap of the primary side of the center-tapped high-frequency transformer; and
a full-bridge converter, wherein a midpoint of an input bridge arm of the full-bridge converter is connected to a secondary side of the center-tapped high-frequency transformer, and an output side of the full-bridge converter is connected with a DC load;
wherein an action sequence of voltage vectors of the high-frequency matrix converter is determined according to a line current amplitude of a motor.
