That guarantees the reg output voltage stays at zero volts during the "off" portion of the switching cycle so the inductor and capacitor can low pass filter the output even at zero load. No preload needed.

WebLoad Regulation: Load regulation is the change in output voltage for a change in the output current. Soft Start: It is important for boost regulators to have a soft-start function that ramps the output voltage in a controlled manner upon startup to prevent excessive output voltage overshoot at startup. Webof topological modiﬁcations to the basic interleaved buck con-verter have been proposed to improve the transient response, while retaining high efﬁciency [9]–[19]. Besides these efﬁciency and transient considerations, the tight load-line regulation requirements present a challenge to the controller design as well. Conventional load-line ... WebA buck converter has a rule that Vin>Vout, so you have a positive voltage 'charging' the inductor, and a negative voltage 'discharging' the inductor. The rate of change in current is dependant on this voltage and inductance. If you want a stable output, the upramp should be as 'high' as the downramp. Otherwise you get a falling or rising average. temp 29588
