Electric automobile three-phase AC charging pile equivalent circuit

The invention provides an electric automobile three-phase AC charging pile equivalent circuit, and relates to the technical field of electrical engineering control. The electric automobile three-phase AC charging pile equivalent circuit comprises a three-phase uncontrolled rectifier bridge +DC/DC converter (1), an inductor (Lf), a resistor (Rc) and a capacitor (Cf). The output end of the three-phase uncontrolled rectifier bridge +DC/DC converter (1) is connected in series with the inductor (Lf). The capacitor (Cf) is connected with the input end of the three-phase uncontrolled rectifier bridge +DC/DC converter (1) so that a complete loop is formed. The capacitor (Cf) is connected in parallel with the resistor (Rc). The electric automobile three-phase AC charging pile equivalent circuit is simple in structure, filtering is performed on DC via the converter, and the electric automobile three-phase AC charging pile equivalent circuit enables one RLC circuit to be equivalent to an electric automobile rechargeable battery in cooperation with other accessories, so that the circuit is more stable.
