| 摘要: |
| 针对带耦合电感的交错并联式双向DC-DC变换器,基于PWM+移相双自由度调制技术,在传统的降阶平均模型的基础上,提出了一种改进型降阶平均建模方法。新模型考虑了耦合电感的功率损耗、磁芯损耗,以及电路拓扑中电感、电容和开关管等元件的寄生参数,比传统模型更精确,能够反映变换器在宽频域范围内的动态性能。在此基础上,根据电压源负载和电阻负载的不同,分别设计了双闭环和三闭环控制器。将新旧2种模型进行理论分析和优势对比,通过一个1.5 kW的原理样机对所设计的控制器进行了实验验证。 |

| Abstract: |
| In this paper, an improved reduced-order average modeling method for the bidirectional interleaved boost with coupled inductors (BIBCI) converter is proposed, based on the PWM and phase-shift dual-degree-of-freedom modulation and traditional reduced-order average model. Considering the power loss of the coupled inductor, the core loss, and the parasitic parameters of the inductors, capacitors, and switches in the circuit topology, the new model reflects the dynamic performance of the converter in a wide frequency domain more accurately than the traditional model. The small-signal model and transfer function are further deduced to provide a basis for the design of closed-loop controllers and have good engineering practicability. According to voltage source load or resistive load, the double-loop or triple-loop controller is designed correspondingly. The two models are theoretically analyzed and compared, and the proposed controller is verified by a 1.5 kW prototype. |
