The objective of this study is the construction of a high power measurement system with NF HS4012 using LabVIEW as the platform of the measurement system for high power transducer. The purpose is to explore high power ultrasound applied to welding and study the size of the ultrasound transducer including its characteristic, energy production and the methods to control energy. The stability and efficiency of the characteristics of the original components and the circuitry of the entire activation system are key points of the investigation for this study.Keywords LabVIEW Á High power transducer Á Ultrasound transducer IntroductionLaboratory Virtual Instrument Engineering Workbench (LabVIEW) is a graphical programming environment. It can be used for sophisticated measurement and test for high power electrical energy by using intuitive graphical icons program connected to external high power instruments. A 550 W high power electrical energy is generated through a high power converter to drive the ultrasound transducer whose mechanical vibration is applied to vehicle leather by high speed mechanical vibrations [1].

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. Keyword: ultrasonic machining driver, BUCK DC chopper circuit, power regulation.

The design of high-voltage wideband amplifiers for excitation of ultrasonic actuators and transmitters has problem with limited slew-rate for full range excitation. This problem is connected with value of total power dissipation of transistors, especially for the advantageous class B stage with common emitters. The power dissipation of transistor is substantially dependent on phase shift of capacitive load especially for high frequency range. This paper solves the dependency of the power dissipation and efficiency on phase shift of load and by this way it enables to solve optimum solution of problems connected with this effect. Especially, the maximum slew-rate can be attained by optimum choose of transistors.
