Abstract:
1. A drive controller for controlling driving of a power conversion circuit comprising a switching element for increasing/decreasing an absolute value of current passing through a coil by repeating electrical ON/OFF operation, so that voltage of power storage unit is converted to a desired value required by power supply unit, the switching element being provided for each positive/negative polarity of output current outputted from a circuit other than the power storage unit, to the power storage unit, wherein the drive controller comprises: energy loading unit for loading energy on the coil through a switching element not corresponding to existing polarity of the output current, after the absolute value has been zeroed by the turn OFF of the switching element corresponding to the existing polarity, but preceding an ON operation of the switching element corresponding to the existing polarity; and OFF-state setting unit for turning OFF both of the switching elements corresponding to and not corresponding to the existing polarity, after an energy loading process.
