技術說明

本專利將提出一再生能源儲釋能供電之單級三電能埠諧振式電能轉換器，提供再生能源埠、電池儲釋能源埠與直流電網埠之三電能埠間的電能轉換。 本專利之三能埠諧振轉換器將具有以下特點: (1)整合交錯式同步整流升壓電路與雙向對稱式諧振轉換器成一單級電路，可減少元件數量並降低電路成本，以提昇電路轉換效率 (2)同步整流升壓電路採用交錯式技術，可使轉換器能承受更高電壓與電流應力並降低輸入電流漣波率 (3)隔離型雙向轉換器可使電池儲釋能源埠與直流電網埠，具雙向電能傳遞功能與電氣隔離特性，提高用電安全性 (4)利用對稱式諧振技術，於雙向功率傳輸，均可使功率開關達成零電壓切換，輸出整流開關達成零電流切換的特點。 This patent proposes a regenerative energy storage power system using a single-stage 3-port resonant converter which enables the energy conversion among the regenerative power port, the battery storage/release port, and the DC power grid port. The patent converter will possess the following features: (1) the integration of interleaved synchronous boost converter and bidirectional symmetric resonant into single-stage, not only decreasing the component number and reducing the cost but also raising the conversion efficiency and realizing the 3-port energy transfer (2) the usage of interleaved scheme on the synchronous rectifying circuit enabling the converter to tolerate higher voltage and current stress and reduce the input current ripple (3) the isolated bidirectional converter design facilitate the electrical isolation between energy storage/release port and DC grid, enhancing the electricity usage security (4) the application of symmetric resonant design equipping the bidirectional power transfer with zero-voltage-switching on the power switches and zero-current-switching on the rectifying switches.
