The invention discloses a resonant converter reverse gain control method, a resonant converter and a storage medium, and belongs to the technical field of power supplies. A primary side bridge arm, a resonant cavity and a secondary side bridge arm which are electrically connected in sequence are arranged in the resonant converter, the resonant converter further comprises a controller electrically connected with the primary side bridge arm and the secondary side bridge arm, and when the resonant converter is in a reverse running state, the switching frequency is selected according to the resonant frequency of the resonant cavity, so that the resonant cavity works in an inductive state; phase-shift control is carried out on the primary side bridge arm and the secondary side bridge arm according to the switching frequency, so that the actual output voltage of the primary side bridge arm reaches the preset ideal output voltage, the output voltage of the primary side bridge arm can be output according to the ideal voltage value, the reverse output capability of the resonant converter is improved, and the circuit loss during reverse conversion is reduced.

    本发明公开了一种谐振变换器反向增益控制方法、谐振变换器及存储介质,属于电源技术领域。本发明在谐振变换器中设置依次电性连接的原边桥臂、谐振腔以及副边桥臂,还包括与原边桥臂和所述副边桥臂电性连接的控制器,在谐振变换器处于反向运行状态时,根据谐振腔的谐振频率选择开关频率,使谐振腔工作在感性的状态;根据开关频率对原边桥臂和副边桥臂进行移相控制,使原边桥臂的实际输出电压达到预设理想输出电压,使原边桥臂的输出电压可按照理想电压值输出,提高谐振变换器的反向输出能力,降低反向变换时的电路损耗。
