摘要
针对双串联谐振双向三端口DC/DC变换器,提出一种可抑制寄生漏感影响的选频解耦控制方案。通过分析输出绕组漏感对两输入端口耦合关系的影响,选择特定开关频率和谐振频率比值,抑制两输入端口之间的功率耦合关系,实现对多输入端口功率解耦控制的目的。分析解耦系统的稳态工作模式,确定变换器不同工作模式下各端口功率特性,并采用移相控制策略实现恒压输出及各端口功率的自动平衡调节。仿真和实验结果验证了上述理论的正确性和控制方案的可行性。
A power decoupling control scheme with selected frequencywas leakage leakage inductance for a dual series resonant bidirectional three-port DC/DC inductance of output-side winding, the coupling power over switch proposed to suppress effect of parasitic converter. By analyzing the influence of frequency and resonant frequency ratio between the two input ports are presented. The steady-state operation of the decoupling system is analyzed to depict the power characteristics for converter ports in different operation modes. A phaseshift control strategy was used to implement constant voltage output and automotive balance power of the three ports. The simulation and experimental results are given to confirm validity of proposed theory and feasibility of the scheme.
