Title of Keynote Speech

Next Generation Residential Solar Photovoltaic Microinverters

Abstract: Concerns regarding climate change because of fossil fuels have expedited the growth of renewable energy sources. Expanding solar power usage in residential networks is a critical step in the decarbonization and clean electricity movement. To achieve a carbon-free grid, providing affordable solar power to the public, through improvements in power density, reliability, and cost-reduction in residential solar systems are essential. This presentation will focus on the research and assessment of next generation microinverters for residential solar photovoltaic (PV) applications. It explores the pathways to increase solar microinverter adoption through a holistic design with advances in efficiency, reliability, power density, and cost. Various topological configurations of the power electronics system will be outlined with the implementation of dual-active-bridge (DAB) based DC-AC converters for single-stage power processing. Innovations in the modulation and analysis techniques to achieve multi-objective designs utilizing wide bandgap GaN devices will be discussed. Active power decoupling solutions will be outlined for high power density and reliability avoiding the use of low-lifetime and large-volume electrolytic capacitors. Improvements in innovative low-profile planar magnetics designs will be presented. Furthermore, the presentation will outline innovative enclosure integrated connector design and packaging to further reduce the size and cost of the microinverter. Finally, a synopsis of the important outcomes, market trends, and future perspectives for residential PV microinverters will be presented.
