Abstract
A DC-DC high frequency boost converter with a supply voltage input (), a boosted voltage output (), a series circuit of an inductor () and a rectifying device () connected in series between said supply voltage input () and said boosted voltage output (), has a switch () connected between ground and a connection node () of said inductor () and said rectifying device (). A control circuit () is provided for controlling said switch (), and a zero inductor current detection circuit () is provided that compares a voltage (U) on said connection node () with a reference voltage (U) and provides a zero inductor current indication (Comp) when both voltages are equal.
