Abstract
A power converter having a Scott-T transformer includes a direct current to alternating current converter configured to have at least two multilevel converters converting input direct current power to alternating current power, a Scott-T transformer configured to operate in medium frequency of several hundreds of Hz to several tens of kHz, to transform a voltage level of the alternating current power from each of the at least two multilevel converters of the direct current to alternating current converter into three-phase alternating current power, and to output the three-phase alternating current power, and an alternating current to direct current converter configured to convert the three-phase alternating current power from the Scott-T transformer to direct current power.
