摘要


本研究為驅動壓電陶瓷馬達,需要設計一功率30W,輸出電壓±150V,頻率120Khz之正弦波驅動電路,電路架構主要包含弦波產生電路、振幅控制電路、功率放大器。弦波產生器主要作用為產生共振頻率之弦波,並可藉由電阻值的變化調整頻率,以多回授帶通濾波器為基礎;振幅控制器可透過外部控制命令控制其輸出弦波電壓振幅大小;功率放大器以AB類並聯推挽式達靈頓放大器作為基礎,藉由組數的增加提升瓦數,可將其弦波訊號之功率提高以驅動壓電陶瓷馬達。並透過所設計之驅動器作為電腦控制端與機構之間的溝通介面,內部微處理器做通訊協定,溝通雙方在傳輸時的資料正確性;而控制器亦可針對不同的控制方式。

This research is design of driver circuit for application of a piezoelectric ceramic motor. Design a power of 30W, the output voltage ± 150V, 120Khz frequency of sine wave drive circuit. A sine wave generator to produce a major role in the resonance frequency of the sine wave, and by adjusting the resistance value of the frequency variation, based on multi-feedback bandpass filter; controller may control commands to control the amplitude of its output voltage amplitude of the sine wave through the external; parallel push-pull class AB power amplifier Darlington amplifier as a basis to enhance the wattage by increasing the number of groups, which can be a sine wave signal of the power increased to drive the piezoelectric ceramic motor. And as a computer-controlled drive is designed through communication interface between the client and the internal microprocessor institutions do protocol, communication between both sides in the transmission of data accuracy; while the controller can control for different ways.
