Output-Impedance Shaping of Bidirectional DAB DC–DC Converter Using Double-Proportional-Integral Feedback for Near-Ripple-Free DC Bus Voltage Regulation in Renewable Energy Systems


This paper investigates the design and implementation of virtual-output-impedance shaping on an inverter-loaded, fuel-cell-battery-powered dc–dc converter system for achieving near-ripple-free dc bus voltage regulation. The strategy is based on the insertion of a second output-voltage feedback loop as can be inferred from the Mason's gain formula. 3 basic modes of virtual-output-impedance shaping (proportional, spinoff, integral) are mentioned and also the closed-loop output-impedance characteristics due to every of them are analyzed in detail and with their Thévenin equivalent circuits derived. Despite the suitability of integral feedback for minimizing converter's output impedance, it can offer rise to an unwanted resonance peak near the converter's crossover frequency, therefore potentially destabilizing the system. The solution to the matter using combination of basic virtual-output-impedance shaping modes and its sensible implementation are discussed. When implemented on a fuel-cell-battery-powered dual-active-bridge dc–dc converter, the second-harmonic distortion of dc bus voltage is shown to possess been reduced by eighty five.five% compared to a conventionally PI-compensated system.
