Abstract
The invention relates to methods of controlling operation of a resonant power converter and to controllers configured to operate according to such methods. Embodiments disclosed include a method of controlling a power output of a resonant power converter comprising first and second switches (S, S) connected in series between a pair of supply voltage lines, a resonant circuit connected to a node between the first and second switches and to an output connectable to an output electrical load, the resonant circuit comprising an inductor and a capacitor, the method comprising: closing the first switch (S) to start a first conduction interval; setting a first voltage level (); setting a first time period; and opening the first switch (S) to end the first conduction interval when a voltage () across the capacitor crosses the first voltage level () and when a time period from closing the first switch exceeds the first time period ().
