Patent abstract
An energy converter is disclosed in which self oscillation mode operation is improved by a closed loop feedback control. The feedback control utilizes the voltage error from the voltage valley in the drain voltage (Vdrain) of the converter switch (1), to determine an error (E(n)) in the time domain. Control circuitry (61, 62, 63) is used to minimize this time-domain error (E(n)) to optimize the control of the switch mode converter.
