當各國政府制定更嚴格的汽車碳排放標準以及燃油車退場時機後，電動車的發展就越來越快速，更多的廠商開始投入電動車產業鏈，無非是看好電動車的未來，目前除了電動車相關技術持續演進外，電動車的成本也持續在下降， 影響電動車市占率的因素最重要的除了成本之外就是電池充電時間的長短，所以電動車電池電壓將由主流的400伏特往800伏特演進，使用800伏特的系統將可以讓充電設施的輸出功率往上提升，以縮短電池充電時間。本研究提出以化合物半導體-碳化矽電晶體組成的功率模組搭配設計的閘極驅動板組成電動車永磁同步馬達驅動器，其規格為最大輸出功率100千瓦，最高電壓800伏特，並同時比較碳化矽電晶體與傳統的絕緣閘極雙極性電晶體特性，以及使用雙脈衝測試方法來驗證碳化矽電晶體切換時的暫態特性，也說明了在驅動碳化矽電晶體時所需注意的地方，並以軟體模擬與在Dyno動力平台上實際量測馬達驅動系統的效能。

When governments around the world formulate stricter automobile carbon emission standards and the timing of the retirement of fuel vehicles, the development of electric vehicles becomes faster and faster. More manufacturers begin to invest in the electric vehicle industry chain, which is nothing more than optimistic about the future of electric vehicles. At present, in addition to electric vehicle related technologies continue to evolve, the cost of electric vehicles also continues to decline. In addition to cost, the most important factor affecting the market share of electric vehicles is the length of battery charging time. Therefore, the battery voltage of electric vehicles will evolve from the mainstream 400 volts to 800 volts. The use of 800 volts systems will increase the output power of charging facilities to shorten battery charging time. This study proposes to use a power module composed of compound semiconductor-silicon carbide transistor and a designed gate driver board to form an electric vehicle permanent magnet synchronous motor driver. Its specifications are a maximum output power of 100 kilowatts and a maximum voltage of 800 volts. At the same time, comparing the characteristics of silicon carbide transistors and traditional insulated gate bipolar transistors, as well as the use of double-pulse test methods to verify the transient characteristics of silicon carbide transistors when switching, it also illustrates what needs to be paid attention to when driving silicon carbide transistors. Also use software simulation and actual measurement of the performance of the motor drive system on the Dyno power platform.
