Effect of Multilevel Inverter Supply on Core Losses in Magnetic Materials and Electrical Machines [PDF]
The effect of multilevel inverter supply on power losses in magnetic cores and electrical machines is studied. A dynamic numerical model for the hysteresis, eddy current, and excess losses in a core lamination is first developed.

A Switching Converter Losses Decreasing Method
A signal timing calculation method to control power switches of bidirectional switching converter (SC) with high efficiency is proposed. The method is applicable for MOSFET-based cascaded boost-buck converter, which has a negative offset current flow at the beginning of each conversion period.
