Abstract
In a control device of a power converter circuit repeating accumulation of energy to an inductor and release of energy from the inductor at each turn on/turn off timing of a switch, a zero cross detecting circuit detects a time when a current flowing through the inductor becomes zero by inputting a voltage between both terminals of the inductor directly without any resistance for detecting the inductor current. There is no electricity loss caused by the resistance for detecting the inductor current and critical mode control of the power converter circuit is precisely carried out.
