Abstract
A converter includes a switching element configured to switch an input voltage, a drive unit configured to drive the switching element, a pulse signal generating unit configured to supply a pulse signal to the drive unit, and a bypass unit configured to connect the switching element and the pulse signal generating unit without involving the drive unit. An operation of the bypass unit maintains the switching element in an on state when the input voltage is switched to a lower voltage and switching of the input voltage is stopped.
