The invention discloses a charger circuit, which comprises a power factor correction module, a resonance power conversion module and a feedback control module, and is characterized in that when the output voltage of the resonance power conversion module changes, the feedback control module is coupled with sampling output voltage hardware to adjust the output voltage of the power factor correction module, so that the circuit always works at a resonance point. According to the technical scheme provided by the invention, the PFC voltage is adjusted through hardware, so that the resonance circuit always works in a resonance point state, and the circuit efficiency is improved.
