摘　　要：提出一种基于AVR单片机ATmega64的超音频感应加热电源的设计方法。介绍了锁相环集成芯片CD4046与单片机结合构成的数字锁相环,给出了实现数字锁相环的算法。功率控制方面通过PI算法调节单片机PWM波输出移相角,实现移相调功。最后通过Matlab/Simulink仿真验证了控制方案的可行性和有效性。The AVR MCU-based design method for superaudio induction heating power was proposed,and the digital phase lock loop （DPLL） constituted by CD4046 （phase lock loop integrated chip） and MCU was introduced and the DPLL algorithm was given.As for the power control,the PI algorithm was used to regulate MCU＇ s PWM wave so that phase-shifting angle can be outputted to realize phase shift modulation.MATLAB/Simulink simulation results verify the feasibility and effectiveness of the control scheme.
