Abstract

The invention discloses an input and output integrated converter of a superconducting energy storage magnet, which can realize the three functions of charging input, variable current output, quenching and energy discharge of a superconducting energy storage magnet L. The converter comprises a full-bridge switch circuit (1), an energy discharging resistor R, a filter capacitor C and a bidirectional chopper circuit (2). The positive electrode of the full-bridge switch circuit (1) is connected with a normally closed contact P2 of a contactor K. A normally opened contact P3 of the contactor K is connected with one end of the energy discharging resistor R. A main contact P1 of the contactor K is connected with one end of the filter capacitor C. The bidirectional chopper circuit (2) is connected to two ends of the filter capacitor C in parallel. The bidirectional chopper circuit (2) is formed by connecting a positive power electronic switch S1, a positive diode D1, a reverse power electronic switch S2 and a reverse diode D2 in series. The superconducting energy storage magnet L is connected to two ends of a branch circuit in series. The branch circuit is composed of the reverse power electronic switch S2 and the reverse diode D2.
