An important trend is the use of plug and play microinverters attached to the PV panel, allowing the so called AC module. However, these converters are subjected to high temperature and humidity. Thus, in order to improve reliability and achieve long lifetime, this work proposes a new topology that provides inductive power decoupling and eliminates electrolytic and even film capacitors, using a single ceramic or mica capacitor. The topology also provides inductor miniaturization and efficiency improvements.
