英文摘要：
A kind of reversely switching dynistor （RSD） electronic device is proposed to form pulse power supplies for power exciter lasers pulses that should be capable of producing within 30 kV -100kV, hundreds of ns pulse width, tens of MW energy. RSDs are triggered by short reverse voltage from the main （power） circuit. During this reverse, the short reverse current pulse passes through the semiconductor structure forming the thin electron-hole plasma layer in the collector junction plane. Then the applied voltage polarity returns to the initial slate where the plasma layer uniformly distributes the gate electron, which injects majority carriers into the base layers of the RSD s structure. Principle and simplified circuit of the platform used for testing the transient current of the high-speed and hlgh-power RSD semiconductor switch are analyzed. The configuration characteristic and operation property of the instrumentation system centered on the self-integrator type Rogowski coil sensor are introduced. Both of the test platform of the transient current of the RSD switch and the measurement system based on the MATLAB software SIMULINK environment are built up for the simulation models. Both simulation and experimental results can verify the truth of the simulation model for the instrumentation system applied to measure the transient current of the RSD switch, which can give great benefits to optimizing the electrical parameters in both the loop of the test platform of the RSD switch and the Rogowski coil sensor measurement system.
