Introduction
Effective galvanic isolation is crucial in high-voltage applications to prevent unwanted leakage currents from flowing between two parts of a system with different ground potentials (GPD) [1]. As depicted in Figure 1 (left), the DC return current from the input to the output can cause a potentia
The core characteristic of the TRI 1(SM) series is a sophisticated reinforced isolation system which is able to withstand high test voltages (8000 VDC for 1s and 3000 VAC for 60s) and working voltages (480 VACrms). Efficiencies up to 84% allow safe operation from –40°C to +85°C without derating.

Power systems designers have, for decades, been limited by the strict guideposts on Classes 1, 2, and 3 circuitries, but the NEC’s newly defined Class 4 power (as laid out in Article 726) will offer a compelling alternative.
Fault-Managed Power Systems and How They Work
To understand the opportunities Clas

AC-DC and DC-DC power modules became a popular method of creating non-standard or custom AC-DC and DC-DC power supplies when they were introduced approximately 30 years ago. Compared to the newer products now available on the market, they were large in size and had relatively low efficiencies. It became a re
