两调节参数双向DC／DC变换器的建模

Dynamic Modeling for a Bi-directional DC/DC Converter with Two Regulative Parameters

PWM加相移控制变换器是将PWM控制与相移控制相结合的高功率密度双向DC/DC变换器,它具有两个调节参数——移相角φ和占空比D。推导了PWM加相移控制的全桥双向DC/DC变换器小信号模型,并通过仿真验证了其可行性。

PWM plus phase-shift （PPS） technique is a technique combining PWM control technique and phase-shift （PS） control technique. The PPS controlled bi-directional DC/DC converters have two regulative parameters, i.e., phase-shift angle φ and duty cycle D. A new technique modeling for PPS controlled full bridge bi-directional DC/DC converters is proposed, and the validity of this technique has been verified by simulation.
