A paral el resonant high voltage power supply based on high frequency AC-link was presented. High power factor and high efficiency were achieved within the quasi-resonant operation mode of the structure. An analysis method for paral el resonant circuit based on the state plan diagram was proposed. Compared to traditional steady-state, simple solvings, intuition, precision and adapt to a wide range of load variation were the advantages. The derivation process of paral el resonance analysis was given. The resonant parameter designs and the principle of control using the state plan diagram method for a module with output character 25 kV,1 A were given. And final y a simulation was taken, the simulation results show that the paral el resonant HVDC convertor based on HF AC-link technology and control ed with the proposed mothod has a stable output (<1%) , switchs at zero current and has a good input current character(<12.5%) and high power factor(0.99).
