Abstract

For the current problems of resent ultrasonic machining driver, for example, output power is single and power regulation is not precise. This paper presents a new type of ultrasonic machining driver based on BUCK DC chopper. The new type of ultrasonic machining driver consists of STM32F106, DDS waveform generating circuit, signal processing circuit and the most important circuit which is BUCK DC chopper circuit. Principle of the power regulation, transmission´s efficiency, the working principle and operating characteristic under current continuous mode of BUCK DC chopper circuit are established in this paper. The parameters related to BUCK DC chopper circuit are calculated. The system of ultrasonic machining driver is simulated by Matlab and related experiments of the driver were carried out. The experiments results show that the driver of new type based on DC chopper can achieved the expect function.
