The ever present trend for the distributed power systems is the pursuit in the higher efficiency and power density. Resonant dc-dc converters can achieve zero-voltage-switching and thus greatly reduce the switching losses, thus the high efficiency and power density can be accomplished. They gain more and more acceptance ...

A silicon Physical Unclonable Function (PUF), which is a die-unique challenge-response function, is an emerging hardware primitive for secure applications. It exploits manufacturing process variations in a die to generate unique signatures out of a chip. This enables chip authentication and cryptographic key generation.

A Ring Oscillator (RO) ...

This invention disclosure addresses the design of noise separator for conducted electromagnetic interference (EMI) diagnosis. Traditional EMI diagnosis is trial-and-error, wasting lots of time and money. Starting from the function design in circuits to practical design on component and layout level, this invention disclosure claims the methods developed in Center ...

Measurements made on power systems are performed with current and voltage signals derived from instrument transformer secondary circuits. The errors introduced by these transformers are a recognized component of input data errors in SCADA and Phasor Measurement Units (PMU). Correcting these errors by in-situ calibration is an expensive option, ...

Interleaving multi-phase PFC to reduce the input ripple current is a very popular technology for the AC-DC switching mode power supply. With smaller input ripple current, the EMI filter size can be reduced so that higher power density can be achieved. However, by applying this interleaving technology for ...
