【Abstract】 The electric vehicle industry has entered a new stage of large-scale rapid development，and the problems such as lack of charging infrastructure and slow charging speed have become increasingly prominent.So， improving charging power and compatiblecharging facilities have become themain focus.Based on thePower Factor Correction （PFC）circuit of the three-phasevehiclecharging system with 80OV voltage platform，the design and analysis ofPFCarecariedout to improve the slow-charge powerand compatibility.Withthecharging mode and discharge mode areanalyzed，and verifying with Prototype verification.Finaly，thePFC circuit design scheme that satisfy nedsof single-phase/three-phase high-power bidirectional conversion circuit，which providesareference for the production design.

【Key Words】electric vehicle；80oV high voltage platform；on-board charging system；single phase/three phase PFC circuit；bidirectional power conversion
