摘　　要：能源互联网中存在越来越多诸如电动汽车等具有“源”“荷”双重身份的电力设备,这类设备大多采用双向DC/DC变换器实现双向功率流动。为了使实验教学紧跟专业技术发展前沿,结合双向Buck-Boost电路和模型化编程手段,完成了双向DC/DC变换器创新实验平台的设计。以电感电流为参考分析了Buck-Boost电路的双向工作模态,对实验平台硬件电路进行了详细设计,并介绍了典型控制策略的模型化软件设计。在此基础上,设计了光伏发电最大功率点跟踪(MPPT)控制实验案例。典型控制实验和光伏发电MPPT控制实验结果验证了实验平台的软硬件设计,也体现出平台的灵活性。There are more and more power equipment with“source”and“load”dual identities such as electric vehicles,and most of these devices use bidirectional DC/DC converters to achieve bidirectional power flow.In order to keep the experimental teaching up to date with the forefront of professional technology development,the design of the innovative experimental platform of bidirectional DC/DC converter was completed by combining the bidirectional Buck-Boost circuit and modeled programming methods.The bidirectional operating mode of the Buck-Boost circuit is analyzed with the inductor current as a reference,the hardware circuit of the experimental platform is designed in detail,and the modeled software design of typical control strategies is introduced.On this basis,an experimental case of maximum power point tracking(MPPT)control of photovoltaic power generation is designed.The results of typical control experiments and MPPT control experiments for photovoltaic power generation verify the hardware and software design of the experimental platform,and also reflect the flexibility of the platform.
