通过功率振荡闭环控制实现双向单相DC-AC变换器的有源功率解耦

A control strategy for the active power decoupling in a single-phase full-bridge-based bidirectional dc–ac converter is proposed in this work. An ac-side auxiliary-circuit three-leg topology is used for the implementation. The proposal makes use of the instantaneous power theory for three-phase systems, applied to single-phase systems. A closed-loop control in the power domain is implemented, by m...
