| Abstract |
In the field of fusion experiments four quadrant converters are needed for the purpose of plasma stabilisation. The inductive load requires a voltage modulation on top of a relative slowly variying current. The power supply frequency response is usually in the order of 3 to 5 kHz, depending on the size of the fusion machine. The demand, as to the output voltage ripple is at an extremely low level (500 ppm). The output power of the amplifier discussed is 800 kW. This paper describes the application of a four quadrant IGBT bridge with passive filter and a linear MOSFET active filter for the purpose of frequency voltage modulation. IGBT bridge voltage control around zero output voltage is critical. A comparision is made with two other possible power supply concepts. |
