Asymmetric current control method for doubly salient electro-magnetic power generation system

The invention discloses an asymmetric current control method of an electro-magnetic doubly salient power generation system, and relates to the field of electro-magnetic doubly salient generators. Before the sector starting position of the sector starts, an upper bridge arm switch tube connected with a phase winding rising in a self-inductance mode in the sector in the controllable rectifier is controlled to be switched on by a gamma electrical angle in advance, and the upper bridge arm switch tube is continuously switched on to be switched off at a beta electrical angle after the sector starting position of the sector; a lower bridge arm switch tube connected with a phase winding with self-inductance declining in the sector in the controllable rectifier is controlled to be switched on at the sector starting position of the sector, and is continuously switched on to be switched off at an electrical angle alpha behind the sector starting position of the sector, and under the default condition, alphagt is obtain
