Disclosed a multi-output type DC/DC converter including: a reactor
connected to a direct-current power supply; a first switching circuit
composed of switches to apply a current to the reactor; a second
switching circuit composed of switches to switch an output from the
reactor to any one of output terminals; output voltage detection sections
to detect voltages of the output terminals; comparison circuits to
compare outputs with a waveform signal of a predetermined frequency; and
an output selection circuit to receive inputs form comparison circuits,
and to select an output of a comparison circuit, the output having the
earliest rise or the earliest fall, so as to generate a control signal
pertaining to on and off of the first and/or second switching circuit,
wherein a current generated by a discharge of energy accumulated in the
reactor is output to any one of the terminals in accordance with the
control signal.
