摘　　要：大功率超声波在工业生产中具有重要的作用。采用PWM控制DC-DC全桥变换电路实现电源输出功率连续调整。针对单台换能器功率不足,采用四路由IGBT构成的D类功率放大器进行空间功率合成的方法实现设备额定功率输出。采用Pspice对设计方案进行了仿真验证,结果表明方案具有可行性。High-power ultrasonic plays an important role in industrial production. The PWM-controlled DC-DC full-bridge conversion circuit is used to continuously adjust the power output power. For the lack of power of a single transducer,four routing class-D power amplifier composed of IGBT are used for spatial power synthesis to achieve the rated power output of the device. The design scheme is verified by Pspice,the result shows that the scheme is feasible.
