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。(A high frequency induction heating power supply based on DSP. MOSFET is now used as a switch device, and the capacity of 60kW/300kHz is expanded in parallel through the inverter.Using multiple chopping technology, the capacity of chopper circuit is increased, and the fuzzy-DPLL composite digital phase locked loop technology based on DSP is applied to the high frequency situation, so that the lock is locked.It has fast dynamic performance and high precision steady state performance. It achieves reliable tracking of load frequency and reliable control of inverter state, and improves inverter.Working efficiency and power factor.)
