本研究為設計並製作具備短路保護與複頻掃瞄控制之超音波驅動器,內容包括使用頻率、諧波干擾、輸出功率與操作電壓範園等等。為降低成本,設計規劃將振盪級與前級驅動迴路模組化,以提高各機型互用率,高功率輸出端亦採用高效率橋式交換式交變迴路,搭配串聯式諧振迴路與複頻掃瞄迴路控制以提高回路轉換效率。更以高速檢知迴路監控高功率輸出及輸出狀態,取代傳統驅動器僅有的保險絲式保護,以保險絲加上二級式保護系統使驅動主機、使用者與工作場所的安全性提高甚多,並降低維修服務成本。
This paper describes the design and production of an ultrasound driver with the functions of short-circuits protection and multi-frequency scanning. Design considerations include frequency, frequency noise, output power and operating voltage, etc. To minimize cost, the circuit design deploys the modulization of the oscillator and the pre-amp, which increases interchangeability. The high output power is produced with a high efficiency bridge switching circuit combined with a series resonance and multi-frequency scanning circuit to control and improve the switching efficiency. In addition, this design includes a high speed detection circuit for constant monitoring of the high frequency output and output status, but also replaces the need for traditional designs using fuse protection. The fuse and 2-level protection system will not only increase safety for the device, the user, as well as the user environment, but also lower overall servicing and repair costs.
