BM1Q0XX series Quasi-Resonant converter Technical Design
... In the case of Quasi-Resonant converters, switching-loss basically does not occur during turn-on, but occurs predominantly during turn-off. To reduce switching-loss when turned off, turn-off speed can be increased by reducing R7 value, but sharp changes in current will occur, which increases the swi ...

Influence of the Snubbers and Matching Transformer on an Optimal
... For the purposes of this analysis, it is assumed that all elements of this circuit (except for the matching transformer) are ideal, and the ripples of the input voltage Ud and the output voltage U0 are ignored. In order to obtain general results, it is necessary to normalize all quantities character ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
