Abstract
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.
