<p>The method involves operating buck-boost converter in a batch mode with quasi resonant switching. The inductor current (iL) or current through down converter switching element (S1) is compared with a reference current (Iref) to amplify control signal (Ureg), so that generation time of reference current before a turn-off pulse of pulse-width modulated switching signal (SigS1) is reached by amplified control signal (Uv) and pulse-width modulated switching signal (SigS2). An independent claim is included for buck-boost converter.</p> |
