本論文發展一雙向五階電能轉換介面，其由太陽能電能轉換介面、儲能電池控制介面與直流-交流雙向轉換介面組成。太陽能電能轉換介面採用一升壓式直流-直流電能轉換器，控制太陽能電池電流以對太陽能電池作最大功率追蹤；儲能電池控制介面為一升/降壓式轉換器，可控制蓄電池充/放電；直流-交流雙向轉換介面採用五階電能轉換器作雙向交流-直流電能轉換。當雙向五階電能轉換介面作直流-交流電能轉換時，可轉換太陽能電池與蓄電池之直流電力到高品質交流電力注入電網，太陽能電池維持最大功率輸出，蓄電池可充/放電以平滑化太陽能電池輸出功率，同時將太陽能電池輸出功率維持在最大功率點；當雙向五階電能轉換介面作交流-直流電能轉換時，可將交流電能轉換為直流電能對蓄電池充電。不論作直流-交流轉換或交流-直流轉換，皆在雙向五階電能轉換介面之交流端產生具有五階變化之交流電壓，並控制輸出電流為弦波電流。本論文將以數位訊號處理器晶片為控制器完成一硬體雛型，並驗證其功能。

This thesis proposes a bidirectional five-level power conversion interface. The proposed bidirectional five-level power conversion interface is composed of a solar power conversion interface, a storage battery control interface and a bidirectional DC-AC power conversion interface. A boost DC-DC power converter is applied for the solar power conversion interface to control the current of solar cell array for maximum power point tracking (MPPT). A boost/buck DC-DC power converter is used for the storage battery control interface to control charging / discharging of battery. The bidirectional DC-AC power conversion interface adopts a five-level power converter for bidirectional AC-DC power conversion. When the bidirectional five-level power conversion interface is used for DC to AC power conversion, the DC power of solar cell array and battery is converted to a high quality AC power injected into the grid. The solar cell array outputs the maximum power, and the battery can be charged or discharged to smooth the output power of solar cell array. When the bidirectional five-level power conversion interface is used for AC to DC power conversion , the AC power of grid can be converted to DC power to charge the battery. The bidirectional five-level power conversion interface generates a AC voltage with five levels and controls the output current to be sinusoidal regardless the direction of power conversion. A digital signal processor controller based hardware prototype is developed to verify the performance of the developed bidirectional five-level power conversion interface.
