APEC 2026 Multimedia Highlights: Bidirectional GaN, Multichip Modules, and Mini Regulators

Why It Matters

These advances enable smaller, more efficient power conversion for solar installations and data‑center GPUs, accelerating cost reductions and performance gains in two fast‑growing sectors.

Key Takeaways

• Renesas' 650‑V bidirectional GaN enables 500 W solar inverter in single stage
• TI's IsoShield modules deliver three‑times higher power density than discrete designs
• Ferric's integrated voltage regulators act as chiplets co‑packaged with GPUs
• Higher efficiency and reduced board space accelerate data‑center power‑management innovation

Pulse Analysis

The emergence of 650‑volt bidirectional GaN devices marks a turning point for solar power conversion. By eliminating the need for multi‑stage topologies, Renesas' reference design cuts component count, reduces losses, and improves reliability—key factors for residential and commercial micro‑inverter markets where space and cost constraints dominate. GaN’s fast switching also eases thermal management, allowing manufacturers to push higher power through smaller footprints.

Texas Instruments' IsoShield multichip packaging tackles a long‑standing challenge in isolated power supplies: achieving high power density without sacrificing isolation safety. By integrating multiple silicon dies within a single package, the new modules shrink board area and lower parasitic inductance, delivering up to three times the density of conventional discrete converters. This breakthrough opens doors for compact medical devices, aerospace electronics, and edge‑computing platforms that demand robust isolation in limited space.

Ferric’s integrated voltage regulator concept reflects a broader industry move toward chiplet‑based system‑in‑package designs. By embedding IVRs directly alongside GPUs, the solution mitigates voltage droop and current spikes that currently force designers to use bulky external regulators. The approach promises faster response times, reduced electromagnetic interference, and significant board‑space savings—critical advantages as data‑center workloads grow more power‑intensive. Together, these technologies illustrate how GaN, advanced packaging, and chiplet integration are converging to reshape power electronics across renewable energy and high‑performance computing.
