| Abstract: | The paper presented an all-digital high-frequency induction-heated-power based on TMS320F2812.The control mode of chopper power adjustment was applied in this system.The power adopted series resonant inverter and the system used IGBT as the power switching device,DSP as the main control-chip to realize power closed-loop control and digital phase-locked control.The system achieved the automatic power adjustment and fast track control of frequency.The experimental results showed that the power system has such advantages as strong anti-jamming,good real-time and stability as well as the small loss of switch and wide adjustment range,which had good development and application prospects. |
