A multi-output type DC/DC converter including: a reactor connected to a
direct-current power supply; a first switching circuit to apply a current
to the reactor; a second switching to switch an output from the reactor
to any one of output terminals; output voltage detection units to detect
voltages of the output terminals; comparison circuits to compare outputs
of the output voltage detection units with a waveform signal of a
predetermined frequency; and an output selection unit to receive outputs
of the comparison circuits as inputs, the output selection unit selecting
an output of a comparison circuit, the output having an earlier rise or
an earlier fall, to generate a plurality of control signals pertaining to
on and off of the first switching circuit and/or the second switching
circuit, the output selection unit treating the plurality of control
signals in accordance with a predetermined priority order when the
outputs of the plurality of comparison circuits change almost at the same
time, wherein a current generated by a discharge of energy accumulated in
the reactor is output to any one of the output terminals in accordance
with the control signals generated by the output selection unit.
