Popis:	This paper focuses on the design of a dual active low-frequency ripple control for a clean-energy power-conditioning mechanism with an aim to achieve both the alleviation of the low-frequency current ripple of clean-energy sources (e.g., solar photovoltaic, fuel cell, etc.) and the improvement of the ac power quality of a power conditioner. First, a simplified circuit for representing both the current-ripple phenomena at the high-voltage bus and the polluted ac output terminal inside a general power conditioner, including a dc-dc converter and a dc-ac inverter, is derived, and the dynamic model of a dual active low-frequency ripple control circuit is analyzed. Moreover, two adaptive linear neural networks are taken as neural filters to generate the compensation current commands, and an adaptive total sliding-mode controller is designed to manipulate the ripple control circuit for injecting respective suitable compensation currents into the high-voltage bus and the ac output terminal of the conditioner. In addition, the effectiveness of the proposed dual active low-frequency ripple control framework is verified by numerical simulations and experimental results.
