Figure 1: The Qorvo SiC FET – a ‘cascode’ of a Si-MOSFET and SiC JFET

The performance of wide band-gap (WBG) semiconductor switches such as silicon carbide cascode FETs (‘SiC FET’ henceforth) (Figure 1) and SiC MOSFETs is closely tied to its package. At the pure technology level, nanosecond switching speed and low specific on-resistance result in very low losses, allowing mu

Wiring up Quantum Circuits with Light

Artistic rendering of the experimental device with the beam optical photons (red) entering and leaving the electro-optic crystal and resonating within its circular portion as well as the generated microwave photons (blue) leaving the device.

­Quantum computers promise to solve challenging tasks in material science and cryptography that will remain out of reach even for the most powerful conventional supercomputers in the future. Yet, this will likely require millions of high-quality qubits due to the required error correction. Progress in superc

­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

­1 watt DC/DC converters with 480 VAC isolation voltage

TRACO POWER’s new TRI 1 and TRI 1SM

  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.
