A New Microinverter Topology for PV Application with Inductive Power Decoupling Capability

An important trend in photovoltaic lines of research is the use of plug and play microinverters attached to the panel, allowing the so called AC module. However, these converters are subjected to high temperature and humidity. In order to improve reliability and achieve long lifetime, this work proposes a new topology, which provides inductive power decoupling and eliminates electrolytic and even film capacitors, using a single ceramic or mica capacitor. A thorough theoretical analysis of the topology is provided and simulation results prove its feasibility and advantages.
