Research of Design and Simulation on Plasma Power Supply of Plasma Sterilizer in A Low-temperature Environment

In the view of the special specification of the plasma sterilizer in a low-temperature environment, the power factor correction （PFC） and the pulse width modulation （PWM） was applied to realize the design of plasma power, which makes the power supply having the characters of simple structure, low cost and high power utilization etc. At last, the main circuits of the power system are simulated by the Saber, which proved the economical and feasibility the whole design.
