The converter has an inductance element and is to be electrically connected to a second capacitive load.

When the pre-stage output DC voltage is raised from the second DC voltage to the first DC voltage, the inductance element outputs a current to the first capacitive load so as to transfer electric energy, which is stored in the second capacitive load, to the first capacitive load.
