Abstract

With solar energy being one of the most essential sources for general energy transition towards renewable sources, the need for light and efficient photovoltaic (PV) inverters becomes crucial. A PV micro-inverter, having the advantage of omitted dc-wiring and modular flexibility becomes attractive. However, single-phase applications cause the drawback of bulky dc-link capacitors required to compensate doubled frequent power fluctuation on the solar module. This paper presents an active power decoupling method without the need of additional switches by modulating a common-mode (cm)-voltage on the filter capacitors of a differential buck inverter. Based on literature, a stability analysis and simulation is performed. The objective of this paper is to investigate the effect of different variations of dc-link voltage and filter capacitor size on decoupling performance and semiconductor losses, aiming for an optimal inverter design.
