The flyback converter is a buck-boost converter with isolation between its input and output. The inductor used in the buck-boost configuration is replaced by a transformer for isolation and storing energy before sending to the output via the output capacitor. The theoretical transfer function of ...

hybrid flyback-Cuk converter (HFC); electric vehicles; efficiency; voltage gain; energy conversion systems1. Introduction The rapid developments in power electronics significantly impact many industrial fields. Converters, such as DC-DC, DC-AC, and AC-DC are widely used to drive and control ...
Standby function description The L5991 automatically detects a light load condition for the converter and decreases the oscillator frequency on that occurrence. The nor- mal (higher) oscillation frequency is automat- ically resumed when the output load builds up and exceeds a defined threshold. This...
