Switching Losses in Synchronous Rectifying Step-Down …

Switching losses, as the name suggests, are losses that accompany switching operation. The symbol PSWH is used. A synchronous switch (high-side or low-side) of a synchronous rectifying step-down converter can be schematically thought of as switching (turning on/off) the voltages VIN and GND.

Analytical Switching Loss Modeling Based on …

Modern wide-bandgap devices, such as SiC- or GaN-based devices, feature significantly reduced switching losses, and the question arises if soft-switching operating modes are still beneficial. For most of the semiconductor devices, only limited information is available to estimate the switching losses. Especially, if a wide operating range is desired, excessive measurements have to be performed
