“…The OCEM design of the ISEG is based on the Pulse Step Modulator (PSM) topology [5,6] already employed by the company on fusion applications [7][8][9]. The ISEG PSM has a modular topology with 28 series connected chopper modules generating a dc voltage square wave modulated at about 5 kHz.…”

“…A diagram of the SPS module is shown in Fig. 3 [12] . Each SPS module consists of a breaker (which can be turned off by an external signal), a diode rectifier bridge, a capacitor bank, an IGBT switch, a freewheeling diode, an resistance capacitance diode (RCD) snubber circuit, a discharging energy circuit, a control board and a drive circuit.…”

The high voltage power supply (HVPS) based on pulse step modulation (PSM) has already been developed for the auxiliary heating system on HL-2A. This power supply consists of many switch power supplies, and its output voltage can be obtained by modulating their delay time and pulse widths. The PSM topology and control principle are presented in this paper. The simple algorithms for the control system are explained clearly. The switch power supply (SPS) module has been built and the test results show it can meet the requirements of the auxiliary heating system. Now, 112 SPS modules and the whole system have already been developed. Its maximum output is about 72 kV/93 A. The protection time is less than 5 µs. The different outputs of this power supply are used for the electron cyclotron resonant heating (ECRH) system with different duty ratios. The experimental results of the entire system are presented. The results indicate that the whole system can meet the requirements of the auxiliary heating system on HL-2A.
