摘要

電磁鐵式磁浮系統常見於需要穩定、快速驅動、定位精度高及無摩擦之機械相關設備。電磁鐵式磁浮系統為由電磁吸鐵、電流驅動器、位置感测器和控制器所組成。本研究專注於電流驅動器的設計，完成一款以升降壓型式之切換式電源作為可變偏壓之類比式電流驅動器。
與傳統推挽式線性放大器相比，本研究所完成之可變偏壓型類比式電流驅動器具有低消耗功率之優點，與脈波寬度調變式電流驅動放大器相比，除了同樣能够在有大電壓，大電流的工作环境下使用，提高磁浮系統力量時間變化率並提升系統頻寬的特性之外，還減少了電路中產生的多餘熱量，避免了不必要的功率损失。
實驗結果顯示在不同負載频率的條件下，本研究所提出之電流驅動控制器動態響應遠優於傳統推挽式線性放大器及脈波寬度調變式電流驅動放大器，消耗功率為推挽式線性放大器的35.39%~44.63%。

Electromagnet Magnetic Levitated System are commonly used in the machinery equipment that requires stable, fast driving, high positioning accuracy, and no friction. The Electromagnet Magnetic Levitated system is composed of an electromagnetic magnet, a current driver, a position sensor and a controller. This research focuses on the design of the current driver, and completes an analog current driver with a buck-boost switching power supply as a variable bias voltage.
Compared with the traditional push-pull linear amplifier, variable bias analog current driver completed in this research has the advantage of low power consumption. It is used in the working environment of high voltage and high current, which not only improves the time change rate of the force of the Magnetic Levitated System and improves the system bandwidth, but also reduces the excess heat generated in the circuit and avoids unnecessary power loss.
The results of experiment show that under the condition of different load frequencies, the dynamic response of the current drive controller proposed in this research is much better than that of the traditional push-pull linear amplifier and pulse width modulation current drive amplifier, and the power consumption is less than that of the push-pull linear amplifier 35.39%~44.63%.
