Control method of electrical discharge machining power supply capable of realizing automatic boosting

The invention provides a control method of an electrical discharge machining power supply capable of realizing automatic boosting. The method comprises steps of rectification, filtration, voltage regulation, pulse generation, pulse detection, pulse regulation and the like. After a voltage regulation circuit generates stable voltage according to rectification and filtration circuits, a pulse high-voltage part is adjusted to be able to realize self-adaptive regulation to match the change of a power supply clearance. According to the control method of the electrical discharge machining power supply capable of realizing automatic boosting, through control on the breakdown self-adaptive pulse power supply capable of realizing automatic boosting, the mask shape can be copied with high precision and the machining efficiency and the machining size precision can be improved in the discharge breakdown process under the condition of gradual clearance change.
