摘要
结合电动汽车充放储一体化电站变流装置的设计要求,着重对由LLC谐振变换器、桥式PWM直流变换器、双向Buck-Boost直流变换器及三电平双向Buck-Boost直流变换器构成的变流装置进行电池的充电仿真及实验,对充电电流、直流转换效率等方面进行比较,分析了各直流变换器的优缺点,并从结构复杂度、控制难度、控制精度、成本等角度选取适用于一体化电站的结构。
The converter of two-stage topology is presented according to electric vehicle charge-discharge and storage integration station requirements.Charging simulations and experiments of the charger consist of LLC resonance circuit,bridge PWM DC converter,hi-directional Buck-Boost converter DC converter and three-level bi-directional Buck-Boost converter DC converter are carried out.The charging current DC convention efficiency are compared,the advantage and disadvantage of each DC converter are analyzed from the structure complexity, control difficulty, control precision and cost.
