多换流器电力电子系统存在于陆上、海上、空中和太空车辆中。在这些系统中，负载转换器对馈电转换器表现出恒定功率负载(CPL)行为，并且往往会使系统不稳定。本文介绍了新型有源减振技术在DC/DC转换器上的实现。此外，提出的有源阻尼法还用于克服CPL引起的负阻抗不稳定问题。PSPICE仿真和实验结果验证了该方法的有效性。
Multi-converter power electronic systems exist in land, sea, air, and space vehicles. In these systems, load converters exhibit constant power load (CPL) behavior for the feeder converters and tend to destabilize the system. In this paper, the implementation of novel active-damping techniques on dc/dc converters has been shown. Moreover, the proposed active-damping method is used to overcome the negative impedance instability problem caused by the CPLs. The effectiveness of the new proposed approach has been verified by PSpice simulations and experimental results.
