The Design Of Ultrasonic Power

Abstract The development of ultrasonic machining technology is rapid for decades. Type holes and cavity machining，cutting，ultrasonic cleaning，ultrasonic processing，and ultrasonic welding have a wider field of research and application，solves many key technology issues ，achieved good results

This paper introduces the domestic and international aspects in the development of ultrasonic power first. Then a detailed analysis of the composition of ultrasonic equipment Key technologies and design difficulties And design a 200w ultrasonic generator which is used in ultrasonic machining .Through the power of analog and digital ultrasound description of the basic circuit，Learn about the frequency of ultrasonic power tracks，power control，steady speed，overvoltage，overcurrent and impedance matching key technologies. Then designed circuits to all parts of the circuit analysis and design. On this basis ，Details of the rectifier circuit，filter circuit，push-pull inverter circuit，impedance ，Ultrasonic generator and the matching design of transducer and PCB design using Protel software ，and then proceed to circuit board production and testing.

Finally，the design characteristics of the circuit of induction have summed up and summarized.

Key words：ultrasonic generator；ultrasonic transducer；frequency tracking；Impedance matching；half-bridge inverter circuit
