Advanced Power Conversion and Energy Management Solutions at TI

July 1, 2025
An impromptu chat with Henrik Mannesson, General Manager at Texas Instruments, about the pivotal role of semiconductors in the renewable-energy transition.

What you’ll learn:

  • Semiconductors are central to the renewable-energy transition, enabling efficient conversion for solar, battery storage, and DC consumption.
  • Single-stage power converters, using wide-bandgap devices like GaN FETs, are improving solar efficiency and reducing system size.
  • Texas Instruments supports these innovations with reference designs, driving grid flexibility and robust energy management.

 

This first of a two-part Inside Electronics podcast series, guest-hosted by technology editor Andy Turudic of Electronic Design, features Henrik Mannesson, General Manager of Grid Infrastructure and Power Delivery Industrial Systems at Texas Instruments (TI). They discuss the evolving landscape of energy infrastructure with a focus on the pivotal role of semiconductors in the renewable-energy transition. All of the content in this pair of podcasts was an impromptu, no-holds-barred, first-time-ever meeting.

After introducing himself and his background, Henrik outlines the shift over the past decade from traditional electromechanical generation methods—such as synchronous generators in coal, nuclear, and hydro plants—to renewable sources, particularly solar, which has moved semiconductors to the center of energy-conversion technologies.

Henrik highlights the convergence of three key trends: the rise of DC-based solar generation, the growing importance of battery energy storage systems (BESS), and the increasing DC consumption by data centers and other digital infrastructure. All require efficient AC-DC and DC-AC conversion to integrate with legacy AC transmission grids.

A significant portion of Andy and Henrik’s talk centers on innovations in power-conversion topologies, specifically the emergence of highly efficient single-stage converters for residential and rooftop solar applications.

Traditional two-stage conversion (AC-DC followed by DC-AC) is being superseded by single-stage designs. They improve system efficiency by eliminating redundant conversion steps that compound each stage’s losses and by reducing passive component count and their associated losses. Henrik notes that these advances are enabled by wide-bandgap devices, such as GaN FETs, which offer low switching losses and support higher switching frequencies, further shrinking converter size and enhancing performance.

TI supports these developments in single-stage conversion with reference designs like the TIDA-010954 "cycloconverter” (see figure). It integrates maximum power point tracking (MPPT) and AC output regulation in a single conversion stage, streamlining residential solar inverter design.

Henrik also emphasizes the need for continued innovation in battery storage and real-time monitoring. These are areas where semiconductors will drive greater grid flexibility, higher renewable penetration, and more robust energy management as the transition to clean energy accelerates.

Please have a listen on your commute, lunch, break, or whenever you have a chance to safely spend about 15 minutes learning where the industry and market is headed in solar and battery electric storage systems. Join us for Part 2 with Henrik and Andy in the next episode of the Inside Electronics podcast, to be linked here. New episodes of the Inside Electronics podcast air every Tuesday, so feel free to add it to your lunch calendar.
