【摘要】：針對全橋隔離雙向變換器移相角調(diào)節(jié)范圍選取問題進行了深入研究。根據(jù)同一傳輸功率下變換器電流應(yīng)力最小原則,確定了移相角調(diào)節(jié)范圍。針對變換器采用全橋移相控制方式時,產(chǎn)生無功環(huán)流的問題進行了定量分析,研究了無功功率的變化規(guī)律。基于全橋隔離雙向變換器,提出了變開關(guān)頻率的蓄電池最優(yōu)充放電管理方案,提高了變換器充放電效率,同時延長了蓄電池使用壽命。最后,搭建了2.5k W實驗平臺并進行了相關(guān)實驗,實驗結(jié)果驗證了以上理論分析的正確性。
[Abstract]:Based on the principle of minimum current stress under the same transmission power, the selection of the range of phase-shift angle adjustment for the full-bridge isolated bidirectional converter is studied. The range of phase shift angle regulation is determined. The reactive power circulation is quantitatively analyzed and the variation rule of reactive power is studied. Based on the full-bridge isolated bidirectional converter, The optimal charging and discharging management scheme of battery with variable switching frequency is proposed, which improves the efficiency of the converter and prolongs the battery service life. Finally, a 2.5kW experimental platform is built and related experiments are carried out. The experimental results verify the correctness of the above theoretical analysis.
