【摘要】：近年來，隨著全球范圍內(nèi)化石能源危機的日趨嚴峻和環(huán)境保護的迫切需求,新能源汽車因?qū)鹘y(tǒng)化石能源的依賴及對環(huán)境影響相對較小，其前景被廣泛看好。我國已把新能源汽車在現(xiàn)代化城市交通系統(tǒng)中的推廣與應(yīng)用列入未來重點發(fā)展目標(biāo)，，十一五、十二五規(guī)劃中，新能源汽車都被列入國家重點發(fā)展與扶持的行業(yè)。針對短途或城市內(nèi)交通，純電動汽車行駛里程受限的缺點相對不突出。但要對傳統(tǒng)燃油汽車構(gòu)成競爭，需大幅增加續(xù)航里程。因此在目前儲能技術(shù)短時間內(nèi)難以有突破性進展的背景下，混合電動汽車是更具有實用意義的解決方案。 針對現(xiàn)有混合電動汽車能量管理系統(tǒng)所存在的功率密度低、可靠性差等問題，提出了一種基于級聯(lián)H橋和矩陣變換器結(jié)構(gòu)的高功率密度變換器拓撲。電池儲能單元和車載內(nèi)燃機發(fā)電單元提供整車驅(qū)動所需要的電功率，二者分別通過級聯(lián)H橋和矩陣變換器與中頻多繞組變壓器輸入側(cè)繞組相連，中頻多繞組變壓器完成整車功率在電源和負載間的靈活、高效傳輸。其中，級聯(lián)H橋電路作為儲能單元控制電路的重要組成部分，在電池充放電過程中，通過均衡電池模塊的動態(tài)電壓，可以改善電池的工作環(huán)境，延長電池的使用壽命。所提出的車載變換器降低了電池的串聯(lián)規(guī)模和電解電容的使用量，可以顯著提高混合電動汽車能量管理系統(tǒng)的功率密度和可靠性。在Matlab/Simulink環(huán)境中建立了相應(yīng)的仿真模型，仿真結(jié)果驗證了所提拓撲結(jié)構(gòu)和相應(yīng)控制策略的正確性。同時搭建了基于新型拓撲的物理樣機平臺，驗證了所制定的控制策略的有效性。
[Abstract]:In recent years, with the increasingly severe crisis of fossil energy and the urgent need of environmental protection, the prospects of new energy vehicles are widely promising because of their dependence on traditional fossil energy and relatively small impact on the environment. In China, the promotion and application of new energy vehicles in the modern urban transportation system have been included in the future key development goals. In the 11th Five-Year Plan and the 12th Five-Year Plan, new energy vehicles are listed in the industries of national key development and support. For short distance or urban traffic, pure electric vehicle mileage restriction is relatively not obvious. However, in order to compete with traditional fuel-powered vehicles, it is necessary to substantially increase the mileage. Therefore, hybrid electric vehicle (HEV) is a more practical solution under the background that it is difficult to make a breakthrough in the current energy storage technology in a short period of time. A high power density converter topology based on cascaded H bridge and matrix converter is proposed to solve the problems of low power density and poor reliability in the existing hybrid electric vehicle energy management system. The battery energy storage unit and the on-board internal combustion engine power generating unit provide the electric power needed for the whole vehicle drive. They are connected to the input side windings of the if multi-winding transformer through cascaded H-bridge and matrix converters, respectively. If multi-winding transformer completes the flexible and efficient transmission of power between power supply and load. As an important part of the control circuit of energy storage unit, the cascaded H-bridge circuit can improve the working environment and prolong the service life of the battery by equalizing the dynamic voltage of the battery module during the charging and discharging process of the battery. The proposed on-board converter reduces the battery size in series and the use of electrolytic capacitance, and can significantly improve the power density and reliability of the hybrid electric vehicle energy management system. The corresponding simulation model is established in the Matlab/Simulink environment. The simulation results verify the correctness of the proposed topology and the corresponding control strategy. At the same time, the physical prototype platform based on the new topology is built to verify the effectiveness of the proposed control strategy.
