中文摘要 | 本論文提出一以電路設計方式來實現空間向量脈波寬度調變法則包含線性以及過調變區域。所提出之法則將以可程式閘陣列(FPGA)的電路設計方式來實現。所設計之空間向量脈波寬度調變控制IC將可以以Altera公司所生產的一顆可程式閘陣列IC來完成。由實驗結果可以得知所設計之IC將會有很好的驅動響應,並且其切換頻率可以設定超過100K赫茲,並且其延遲時間也是可以調整。其輸出的基頻能夠設定超過2000赫茲。此設計之空間向量脈波寬度調變IC能夠被含蓋在數位電流控制回路當中。而且此IC晶片也能夠提供一個簡單而且低成本的硬體設計在高效能的交流驅動器中。 |
英文摘要 | This paper presents a new circuit design scheme of the space-vector pulse-width modulation (SVPWM) strategy, including linear and overmodulation ranges. The proposed scheme has been developed using the state-of-the-art field-programmable gate array (FPGA) technology. The SVPWM control integrated circuit (IC) can be realized by using only a single FPGA (Cyclone) from Altera, Inc. Experimental results show that this controller can present an excellent drive performance and its switching frequency, which can be set to over 100kHz, is adjustable as well as its deadtime. The output fundamental frequency can be adjusted over 2000Hz. This SVPWM IC can be included in the digital current control loop for stator current regulation. The IC also provide a simple hardware and low cost for high-performance ac drives. |
