A kind of high-voltage inverter power supply for electron beam precision micro machining equipment is introduced. The system is based on the current transformation way of AC DC AC AC DC. Its intermediate inverter link is intermediate frequency inverter which is composed of two phase parallel half-bridge inverter, this can solve the problem of discontinuous current when is in light load. Because it is medium frequency inverter, the realization of energy transfer is intermediate frequency, so the cost of the equipment is reduced. In the high-voltage side, the over-voltage can be effectively suppressed by using the pressure sensitive resistance. The mathematical model of the inverter high-voltage power supply is built by the simulation software PSIM. The simulation results show that the performance of the power supply can meet the expected design target and guarantee the welding quality of the EBM.
