| Abstract: | The control system of the PSM high voltage power supply in the HL-2A tokamak power supply was presented. The control system based on DSP & FPGA, including parts of driving, communication, computation and feedback, generated 112 pulses to make IGBT modules turn on or off quickly in order to keep the output voltage steady. The upper computer was based on VB and could set experimental parameters then communicated to DSP by CAN BUS. DSP & FPGA completed the computation and feedback. The composing and debugging of software code and the testing of the whole system were accomplished. The results showed that the control system meets the requirements. |
