    摘要： A power converter which may be used in a resonance power transmission system and an apparatus for transmitting a resonance power are provided. According to an aspect, a power converter in a resonance power transmission system may include: an input end configured to receive a direct current (DC) voltage of a predetermined level; a first power converter configured to convert the DC voltage of a predetermined level to an alternating current (AC) signal using a first switching pulse signal having substantially the same frequency as a resonant frequency; a second power converter configured to convert the DC voltage of a predetermined level to an AC signal using a second switching pulse signal having an opposite phase to the first switching pulse signal; a first short circuit configured to reduce or eliminate an odd harmonic of the AC signal outputted from the first power converter, and to provide the AC signal where the odd harmonic is reduced or eliminated to a source resonator; and a second short circuit configured to reduce or eliminate an odd harmonic of the AC signal outputted from the second power converter, and to provide the AC signal where the odd harmonic is reduced or eliminated to the source resonator.
