Abstract
A control circuit includes: a converter configured to convert alternating current (AC) power into direct current (DC) power, an inverter configured to generate driving power of at least one motor using the converted DC power, and a first core formed by winding a coil by a number of windings determined in correspondence with an impedance of the at least one motor. The number of windings is determined such that an impedance of the first core is inversely proportional to the impedance of the at least one motor and a driving power line for driving the at least one motor passes through a center of the first core.
