Abstract
A wireless power transmitter includes: a power supply configured to supply a driving power; a first power transmitter including first bridge switching elements forming a first bridge circuit, and configured to receive the driving power to transmit a first power, wherein a magnitude of a first input voltage applied to the first bridge circuit is determined by a duty of at least one of the first bridge switching elements; a second power transmitter including second bridge switching elements forming a second bridge circuit, and configured to receive the driving power to transmit a second power, wherein a magnitude of a second input voltage applied to the second bridge circuit is determined by a duty of at least one of the second bridge switching elements; and a controller configured to output first and second power transmitting control signals respectively controlling the first bridge switching elements and the second bridge switching elements.
