Abstract
Gyrotron plays an important role in the research of electron cyclotron resonance heating (ECRH) on Tokomak. The high-frequency switched power supply technology and pulse step modulation (PSM) technology are used in the development of the all solid high-voltage body power supply (BPS) for 1Â MW/105Â GHz Gyrotron on ECRH system. Firstly, the basic structure of the BPS and its control system are introduced. Secondly, the software control algorithm of voltage stabilization and modulate method are developed. Finally, the design is verified by the experiments. The experimental results of the single pulse mode, the multi-pulse modulation mode and the six-level preset mode, are shown. The output voltage of the power supply can reach 35Â kV and the current at about 200Â mA, which are adjustable in the full range. The maximum modulation frequency can reach 1Â kHz and the front edge of the pulse can be adjust from 0 to 3Â ms and the accuracy of the output voltage is less than 100Â V. The results show that the control method is feasible and can be applied to other high power microwave sources.
