| 摘 要： | 介绍了一种基于DSP的高频感应加热电源。现以MOSFET为开关器件,并通过逆变器并联扩容为60kW/300kHz。采用多重斩波技术,增大了斩波电路的容量,将基于DSP的fuzzy-DPLL复合数字锁相环技术应用在高频场合,使锁相有快速的动态性能和高精度的稳态性能,实现了对负载频率的可靠跟踪及对逆变状态的可靠控制,提高了逆变器的工作效率和功率因数。

| Abstract: | An induction heating power based on DSP is introduced.A 60 kW/300 kHz inverter which adopts MOSFET as switch devices and is composed of three inverter bridges with capacity 20 kW is developed.The multiple chopper is used in order to increase the power of the inverter.It proves that the advanced induction heating frequency-tracking system based on fuzzy-DPLL can track the load resonant frequency rapidly and accurately. |
