摘要

各种各样的电源以不同的电压、电流和功率输出能力分布在电力系统中。为了提高效率和可靠性，它们必须通过并联DC-DC转换器协同使用。提出了一种基于无源控制的升压变换器并联调节方法。结果表明，对各变换器采用基于无源性的控制可以保证整个系统的渐近稳定。通过仿真和实验对系统的稳定性进行了讨论。根据反馈增益的设置，检查了瞬态和稳态特性。

Regulation of Parallel Connected Boost and Buck Converters by Passivity-Based Control

Variety of power sources are distributed in power systems at various classes of voltage, current, and power output capacities. They must be cooperatively used through parallel connected DC-DC converters for high efficiency and reliability. This paper proposes a passivity-based control for the regulation of parallel connected boost and buck converters. It is shown that the application of passivity-based control for each converter guarantees asymptotic stability of the whole system. The stability of the system is discussed through simulation and experiment. Transient and steady-state characteristics are examined depending on the setting of feedback gain.
