Next-Gen Power Architectures in Solar Power: GaN and Bidirectionality enable Single-Stage topologies in Microinverters

As electrification expands across sectors like solar energy, electric vehicles, and smart grids, the focus is shifting toward architectures that are more efficient, more compact, and more intelligent. Trends like fewer conversion stages, higher voltage buses, and bidirectional energy flow are reshaping the design landscape. In this conversation, we speak with Marco Ruggeri, Senior Manager of the Power System Architecture Team and Pietro Scalia, the Head of System Application and Marketing for Power , both of Renesas Electronics. They share insights into Renesas’ single-stage, bidirectional GaN-based microinverter and how it could redefine the future of energy conversion and distributed power systems.
