Abstract: A resonant converter including a full-bridge switch circuit, a resonant circuit, a transformer, a rectifier circuit, a current sensor and a controller is provided. The full-bridge switch circuit includes switches. The resonant circuit is electrically connected to the full-bridge switch circuit and includes a resonant inductor. The transformer includes primary and secondary windings, and the primary winding is electrically connected to the resonant circuit. The rectifier circuit is electrically connected to the secondary winding. The current sensor is electrically connected to the resonant circuit. When a current flowing through the resonant inductor passes through the current sensor, the current sensor generates a current differential signal correspondingly. The controller performs double integration on the current differential signal to acquire an electric charge signal and controls operation of the switches of the full-bridge switch circuit according to the electric charge signal and the input and output voltages of the resonant converter.

Abstract: A charging system includes a power input part, an inverter, a DC bus, at least one charging device, a first bidirectional energy storage module, a second bidirectional energy storage module and an intelligent controller. The charging device includes a DC/DC converter and a charging gun. A first bidirectional DC/DC converter of the first bidirectional energy storage module receives and converts the DC power from the inverter for charging a first battery, or converts a first storage electric energy of the first battery for the charging device. A second bidirectional DC/DC converter of the second bidirectional energy storage module receives and converts the electric energy outputted by the DC/DC converter of the charging device for charging a second battery, or converts a second storage electric energy of the second battery for the charging device. The intelligent controller controls operations of the first bidirectional DC/DC converter and the second bidirectional DC/DC converter.
