   文中從雙向dc dc變換基本單元入手，針對某大型車載電源系統(tǒng)設計了一種新型雙向dc dc變換器拓撲電路，降壓變換采用移相全橋式zvs ? pwm功率變換，升壓變換采用推挽式dc dcboost功率變換。
2. In this strategy , an mc is first transformed into an equivalent topology resulting from the combination of a rectifier and an inverter , then , the dtc and the current space vector modulation are respectively performed on the inverter and the rectifier sides , and the strategies on the two sides are finally synthesized and changed into the control signals of the nine bidirectional switches in mc
   該策略先將矩陣式變換器等效成整流器和逆變器的組合，然后在逆變側進行直接轉矩控制，在整流側進行電流空間矢量調制，最后將兩側的策略進行綜合，并轉化成矩陣式變換器9個開關的控制信號。
3. It's difficult to find bidirectional switch in a sentence. 用bidirectional switch造句挺難的
