摘要
随电动汽车使用量增加,V2G模式得到更多关注。主要设计V2G应用中的双向DC/DC变换器,从电路工作原理、电路参数、控制策略等方面详述。电路采用切换开关的方式,使单向电路实现双向功能,但同时也带来电压增益范围窄、控制算法输出不稳定等问题。针对这些问题,电路参数基于反向放电过程设计,利用模糊算法和混合控制构建电路的控制策略。最后,搭建实验样机,验证所提设计方法的有效性。
With the widespread use of electric vehicles,the V2G model gets more attention.It mainly described the design of bi-directional DC/DC converter in V2G application, including circuit working principle, circuit parameter and control strategy and so on.Transfer switches are used to enable one-way circuit to achieve bi-directional functionality. But, at the same time, there are many issues,such as narrow voltage gain range,unstable control algorithm output.For these problems, the circuit parameters are designed based on the reverse discharge process.And it uses the fuzzy algorithm and the hybrid control to construct the control strategy of the circuit. Finally, the test prototype is set up to verify the effectiveness of the design method.
