Power Integrations, a provider of high-voltage integrated circuits for energy-efficient power conversion, announced how its advanced PowiGaN technology is set for advanced electric vehicle (EV) and charging systems.
While previously highlighted for AI data centers, the same breakthroughs in efficiency and power density translate directly to EV powertrains, onboard chargers, and megawatt-class fast chargers.
As EV platforms increasingly adopt 800-V / higher-voltage architectures to reduce losses, lower weight, and enable faster charging, Power Integrations’ latest 1250 and 1700-V GaN devices offer a compelling value proposition:
- A single 1250-V PowiGaN switch can outperform stacked 650-V GaN FETs or competing 1200-V SiC devices in power density and efficiency, reducing component count and thermal burden in EV systems.
- The InnoMux2-EP family, featuring an integrated 1700-V PowiGaN switch, supports > 90% efficiency for auxiliary and control functions in high-voltage EV designs.
- These breakthroughs build on Power Integrations’ track record of over 175 million PowiGaN devices deployed across fast chargers, renewable inverters, and EV ecosystems.
“EV architectures are rapidly evolving toward higher-voltage systems to meet power demands,” said Roland Saint-Pierre, VP of Product Development at Power Integrations. “Our 1250 and 1700-V GaN solutions enable EV designers to push efficiency and power density farther than ever before — making more compact, reliable, and lighter power electronics possible.”
In one-to-one comparisons, the new GaN devices deliver > 98% efficiency in target topologies while reducing size, switching losses, and system complexity without compromising reliability. This positions PowiGaN as a strong contender to displace conventional SiC and multi-FET architectures in demanding EV power domains.
Power Integrations is actively collaborating with automotive and infrastructure partners to validate PowiGaN’s real-world performance across high-voltage EV platforms and charging stations.
