摘要
众所周知,今天汽车使用的能源来自燃料,这对环境产生污染。科学家们预测未来石油的数量将会减少。目前,科学家和工程师们正在寻找新的能源来补偿石油。对环境不造成危害是第一要务。为了克服这个问题,电动汽车是流行的解决方案。本文提出了一种适用于电动汽车的简化再生式升压变换器。提出了一种双开关升压变换器,用于在再生模式下为充电电池供电。电池电压为288 V (12V, 24节电池),增加到450 V供三相逆变器供电。介绍了空间矢量PWM逆变器驱动三相/ 50hz / 230v / 20kw异步电动机。仿真结果验证了该方法的可行性。
The simplified regenerative boost converter for electric vehicle applications
It is known that energy source used in car today comes from fuel, which generates pollution to the environment. The scientists have forecasted that the amount of oil will be decreasing in the future. In the present, scientists and engineers seek for new energy sources to reimburse oil. Causing no harm to the environment is the first priority. To overcome this problem, the electric vehicle is the popular solution. In this paper, the simplified regenerative boost converter for electric vehicle applications is proposed. The two-switch boost converter is presented for supplying the power to charge batteries on the regenerative mode. The battery voltage is 288 V (12V, 24 batteries), was increased to 450 V for supplying the 3-phase inverter. The space vector PWM inverter is introduced to driving the 3-phase/50 Hz/230 V/20 kW induction motor. The feasibility of the proposed method is confirmed by simulations.
