description	The invention provides an electric spark machining pulse power supply based on a three-level Cuk circuit and a machining method. The electric spark machining pulse power supply comprises a three-level Cuk main power circuit, a direct-current voltage source, an FPGA control circuit and a drive circuit, and the three-level Cuk main power circuit is used for being connected with an electric spark machining gap to achieve electric spark machining. The direct-current voltage source is used for outputting adjustable direct-current voltage to supply power to the three-level Cuk main power circuit, the FPGA control circuit is used for generating a PWM signal to enter the driving circuit, and the driving circuit is used for processing the PWM signal and then generating a driving signal to control on and off of a switching tube of the three-level Cuk main power circuit. According to the invention, the switching frequency of the system is equivalently improved, the voltage and current ripples are greatly reduced, the ty
