Single-phase inverter suffers from doublefrequency power ripples in the input side transferred there from the ac-side. To mitigate this ripple, two types of power decoupling approaches can be applied: passive power decoupling and active power decoupling. We present a technique of passive power decoupling realized by modifying the control strategy. The main idea is to produce the timevarying shoot-through duty cycle to charge and discharge impedance capacitors when needed in the desired sequence for mitigating input power ripple without deteriorating the output power quality. The main contribution of the paper is in the determination of the parameters of a regulator taking into account the dynamic feature of the quasi-Z-source network. The validity of the proposed control strategy was confirmed by simulation results in PSCAD. The results show that this strategy can be applied for practical applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
