DECO Unveils mmWave Wireless Isolation for High-Voltage Energy Systems At SNEC 2026

At SNEC 2026 in Shanghai, DECO debuted its self-developed mmWave wireless isolation chips and modules. As PV and storage systems push toward higher voltages and power densities, the industry faces complex electromagnetic challenges from SiC and GaN devices. DECO’s non-contact mmWave transmission architecture replaces traditional coupling with a wireless signal path, providing a safer, more stable isolation solution for inverters, PCS, and SST solid-state transformers.

By eliminating the parasitic parameters and aging risks of traditional devices, DECO has set a new industry standard. Its hardware delivers a measured CMTI of 400 kV/μs to withstand extreme switching spikes and has cleared rigorous testing, including 30 kVrms surge tests, 25 kVrms/60s withstand voltage, and a 4-month 10 kVrms TDDB test with zero failures. The technology is highly versatile, supporting 1–2 MHz+ frequencies for GaN applications and providing low-latency, high-reliability control for mid-to-high voltage SiC devices, helping to significantly shrink passive component sizes.

DECO’s solution signals a transition from passive capacitive/inductive coupling to micro-wireless transmission. By leveraging non-contact transmission to minimize parasitic capacitance, the technology eliminates high-frequency leakage and signal distortion. This innovation provides manufacturers of PV and energy storage systems with a path to higher integration, superior anti-interference safety margins, and a faster transition toward digital, compact, and sustainable energy solutions.
