Abstract
(EN) The invention discloses a method for realizing PFC only through primary side phase shift control. The method is based on the topology of a traditional wireless charging system, and removes a traditional PFC circuit, so that the power grid voltage is subjected to uncontrolled rectification to form the power frequency voltage to directly supply power to the primary side inverter of the wireless charging system, and the PFC function is achieved only through primary side phase shift control. Compared with traditional topology, an additional PFC circuit is omitted, PFC can be achieved only throughprimary side modulation, and the method is simple in structure, high in efficiency and low in cost.
(ZH) 本发明公开了一种仅通过原边移相控制实现PFC的方法，该方法是在传统无线充电系统拓扑的基础上，去除传统PFC电路，使电网电压经过不控整流成工频电压直接给无线充电系统的原边逆变器供电，仅通过原边移相控制实现PFC功能，本发明的方法相比于传统拓扑，省去了额外的PFC电路，仅通过原边调制即可实现PFC，结构简单、效率高、成本低。
