Abstract: A control apparatus for a DC-to-DC converter includes a switching controller working to selectively perform a first control task and a second control task. The first control task is to control on-off operations of switching devices of the DC-to-DC converter not to have at least one of an all-on period and an all-off period. The all-on period being a period of time in which all the switching devices are turned on. The all-off period is a period of time in which all the switching devices are turned off. The second control task is to control the on-off operations of the switching devices to have both the all-on period and the all-off period. The switching controller works to change the first control task to the second control task before a current mode is switched from a continuous current mode to a discontinuous current mode.
