Less-conventional low-consumption galvanic separated MOSFET-IGBT gate drive supply [PDF]

, 2017
A simple half-bridge, galvanic separated power supply which can be short circuit proof is proposed for gate driver local supplies. The supply is made while hacking a common mode type filter as a transformer, as the transformer shows a good insulation, it

Design Guidelines for High-Power and High-Frequency Transformers

2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019
In power electronics, the tendency to increase power and frequency (in the range of several MHz) has become an actual concern and leads to challenging design of the magnetic components. The traditional design methods need to be adapted to this demand, since high frequency effects in the core behavior need to be considered, and parasitic elements play a
