摘要
A valley inductance current polarity change in a pulse width modulated circuit charged with an inductive charge is detected by comparing respective times that a first output of the circuit charged with an inductive charge and a second output of a pulse width modulated reference circuit with no inductive charge reach an output level. Responsive thereto, control over operation of the pulse width modulated circuit charged with an inductive charge is made with respect to switching to a pulse skipping mode of operation or keeping the pulse width modulation mode of operation.
