Impedance matching device of electronic switch controllable self-recovery circuit

The invention relates to an impedance matching device of an electronic switch controllable self-recovery circuit, which comprises a lightning arrester module, a switch module and an impedance matching module, the lightning arrester module and the switch module are connected between a high-voltage direct-current positive bus and a high-voltage direct-current negative bus, so that impedance matching of the electronic switch controllable self-recovery circuit is realized, and a value condition of the impedance matching module is given. According to the impedance matching device of the electronic switch controllable self-recovery circuit, through the circuit structure design of the impedance matching device, the impedance matching of the electronic switch controllable self-recovery circuit is realized, and the problems that a charge rate is reduced when a lightning arrester controlled element is connected with the electronic switch and a damping loop of the electronic switch in parallel, so that the overall servi
