1. A resonance power transmitter comprising:
- a voltage controller configured to receive an input of an alternating current (AC) signal of a first frequency band, and to output a direct current (DC) voltage of a predetermined level;
a power converter configured to convert the DC voltage to AC power, by a switching pulse signal of a second frequency band;
a source resonator configured to transfer the AC power to one or more resonance power receivers; and
a source controller configured to control a signal level of the DC voltage based on a reflected power and the number of resonance power receivers.
