Here’s a step-by-step design of a resonant-coupled inductor employed in a PFC EMI filter that doesn’t impact power factor. Over the past 40 years many of my designs included Power Factor Correction ...

Designers have a choice between semi-bridgeless and interleaved PFC pre-regulators. The semi-bridgeless removes half the bridge-rectifier losses, whereas the interleaved PFC can reduce I2R losses up ...

Advanced semiconductor technology allows an increasing number of transistors to be integrated onto ever-smaller silicon chips. This increases the power density, however, and presents power-management ...

Interleaving isolated and nonisolated power stages is a well understood design technique within the power supply design industry. By far the most widely applied interleaved topology is the multiphase ...
