Multiple output converter and method for controlling the same

A multiple output converter comprising:

• an input unit having at least one first switch;
• a transformer unit configured to convert a magnitude of power received from the input unit;
• and
• an output unit having a plurality of output terminals which are configured to receive the power from the transformer unit, wherein each of the plurality of output terminals has each of a plurality of second switches, respectively, and is synchronized with a pulse width modulation (PWM) control signal of the at least one first switch and the plurality of second switches are controlled in a time division multiple control manner,
• wherein the multiple output converter further comprises a feedback circuit unit configured to detect a level of the power of each of the plurality of output terminals for independently controlling magnitudes of the power of each of the plurality of output terminals.

A multiple output converter comprising:

• a power conversion circuit including,
• an input unit having at least one first switch,
• a transformer unit configured to convert a magnitude of power from the input unit,
• an output unit having a plurality of output terminals, which are configured to receive the power from the transformer unit, and
• a second switch unit having a plurality of second switches, wherein each of the plurality of second switches is installed in each of the plurality of output terminals, respectively, and is controlled in a time division multiple control manner;
• and
• a switching control unit configured to transmit a pulse width modulation signal to the at least one first switch and the plurality of second switches for controlling the at least one first switch and the plurality of second switches in the time division multiple control manner,
• wherein the switching control unit is configured to operate the at least one first switch at a frequency fs, and
• wherein each of the plurality of second switches, having N-number switches, is operated at a frequency fs/n so that the switching control unit controls all of powers of the plurality of output terminals in the second switch unit over one N-time period.
