摘　　要：针对目前大功率超声波电源采用模拟控制电路存在精度低、动态响应慢、参数整定不方便等缺点,采用单片机8089组成智能控制的超声波电源系统。提出了基于SPWM技术的双闭环控制策略和应用单片机实现软锁相的工作原理和软件思想,使整个超声波电源实现了低损耗、高功率因数,优化了电路的整体性能。To overcome some disadvantages of low precision, slow dynamic response, unconvenience parameter adjust existing in high-power ultrasonic power supply,it appfies intelligent control composed of 8089 microcontroller isproposed. The article introduces the modulation principle of SPWM,the composition of high - power ultrasonic power system applying the single chip computer to realize the soft of phase lock loop,the mechanism of work and the software thought. It realizes the low loss,high power factor and the whole performance of the circuit is developed.
