The four-switch Buck-Boost converter applied to a fuel cell system can theoretically achieve a higher efficiency under the traditional two-mode control. However, in fact, the dynamic performance of the system is poor due to the influence of a voltage gain blind zone in the process of transition between the two modes, which greatly reduces the operation stability of the converter. In high-power applications with large current, the interleaving technology is usually used to reduce the inductor current ripple and increase the power density of the converter. Therefore, the smooth mode transition of a four-phase interleaved four-switch Buck-Boost converter is taken as a control objective. First, the topology of the converter is introduced, and its basic mathematical relationship is obtained. Then, the reason for the voltage gain blind zone of the converter is analyzed using a graphical method, and a control strategy is proposed to eliminate the blind zone and realize the smooth mode transition based on the traditional three-mode control strategy. In the dynamic process, the changes in duty cycle are minimized and the inductor ripple current is also optimized, which improves the efficiency and stability of the converter. Finally, the effectiveness of the proposed control strategy was verified by experimental results.

应用于燃料电池系统的四开关Buck-Boost变换器在传统的两模式控制下理论上可以获得更高效率,但是实际上,在2个模式切换的过程中,受电压增益盲区影响,系统的动态性能较差,大大降低了变换器工作的稳定性。在电流较大的大功率场合,为了减小电感电流纹波,提高变换器的功率密度,通常会在变换器中使用并联技术。基于此,以四相交错并联的四开关Buck-Boost变换器的模式平滑切换为控制目标,首先介绍变换器的拓扑结构,得到变换器的基本数学关系;接着使用1种图形化方法分析了变换器的电压增益盲区产生的原因,并在传统三模式控制策略的基础上提出1种消除盲区、实现模式之间平滑切换的控制策略,在动态过程中实现了占空比变化量的最小化,电感电流性能也得到了优化,变换器的效率及稳定性得以提高;最后通过实验验证了该控制策略的有效性。

应用于燃料电池系统的四开关Buck-Boost变换器在传统的两模式控制下理论上可以获得更高效率,但是实际上,在2个模式切换的过程中,受电压增益盲区影响,系统的动态性能较差,大大降低了变换器工作的稳定性。在电流较大的大功率场合,为了减小电感电流纹波,提高变换器的功率密度,通常会在变换器中使用并联技术。基于此,以四相交错并联的四开关Buck-Boost变换器的模式平滑切换为控制目标,首先介绍变换器的拓扑结构,得到变换器的基本数学关系;接着使用1种图形化方法分析了变换器的电压增益盲区产生的原因,并在传统三模式控制策略的基础上提出1种消除盲区、实现模式之间平滑切换的控制策略,在动态过程中实现了占空比变化量的最小化,电感电流性能也得到了优化,变换器的效率及稳定性得以提高;最后通过实验验证了该控制策略的有效性。

The four-switch Buck-Boost converter applied to a fuel cell system can theoretically achieve a higher efficiency under the traditional two-mode control. However, in fact, the dynamic performance of the system is poor due to the influence of a voltage gain blind zone in the process of transition between the two modes, which greatly reduces the operation stability of the converter. In high-power applications with large current, the interleaving technology is usually used to reduce the inductor current ripple and increase the power density of the converter. Therefore, the smooth mode transition of a four-phase interleaved four-switch Buck-Boost converter is taken as a control objective. First, the topology of the converter is introduced, and its basic mathematical relationship is obtained. Then, the reason for the voltage gain blind zone of the converter is analyzed using a graphical method, and a control strategy is proposed to eliminate the blind zone and realize the smooth mode transition based on the traditional three-mode control strategy. In the dynamic process, the changes in duty cycle are minimized and the inductor ripple current is also optimized, which improves the efficiency and stability of the converter. Finally, the effectiveness of the proposed control strategy was verified by experimental results.
