The performance of wide band-gap (WBG) semiconductor switches such as silicon carbide cascode FETs (‘SiC FET’ henceforth) [1] (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 much

Wiring up Quantum Circuits with Light

INSTITUTE OF SCIENCE AND TECHNOLOGY AUSTRIA

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

Safe isolation and Low Power consumption in High Voltage Digital Control Applications

Jiaxin Tian, Senior Staff Product Application Engineer; Dr. Narayanaswamy Swaminathan, Staff Product Definition Engineer; and Dr. Diogo Varajao, Head of Technical Marketing of Isolation ICs, all at Infineon Technologies

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
