A power circuit, a power control method, a compound power circuit and an electronic device are provided. The power circuit includes an inverter circuit for converting a first DC signal of the DC power source to a first AC signal, a resonant circuit for regulating the first AC signal, an isolation transformer for converting the regulated first AC signal to a second AC signal, a rectifier circuit for converting the second AC signal to a second DC signal and outputting the second DC signal to a load circuit, and a control circuit for generating a first control signal based on rise and/or drop of the first AC signal voltage and/or rise and/or drop of the second AC signal voltage; the rectifier circuit regulates the second DC signal based on the first control signal.
