Abstract
A power converter includes a primary side circuit, a secondary side circuit, a transformer, and a controller. A primary side of the transformer is connected to the primary side circuit, and a secondary side of the transformer is connected to the secondary side circuit. The primary side circuit includes a resonant circuit. The secondary side circuit is configured to supply electric energy to the transformer. The transformer is configured to supply the electric energy to the primary side circuit. The primary side circuit is configured to convert the electric energy. The controller is connected to the secondary side circuit, and is configured to control, in a control cycle, the secondary side circuit to supply the electric energy to the transformer. Duration of the control cycle is greater than or equal to duration of a resonance cycle of the resonant circuit.
