Abstract: A current meter measures a current value associated with input power inputted to a code modulator. A code modulation circuit modulates the input power to generate a code-modulated wave by code modulation using a modulation code based on a code sequence, and transmits the code-modulated wave to the code demodulator via a transmission path. A control circuit controls the code modulation circuit. The code modulation circuit has operation modes different from each other depending on a direction of the input power, and a direction of the code-modulated wave to be generated. The control circuit generates waveform information indicating variations of direction of the input power over time, based on the current value measured by the current meter, and determines the operation mode of the code modulation circuit based on the waveform information.

Abstract: A code modulator transmits power to at least one code demodulator via a transmission path. The code modulator is provided with: a code modulation circuit to which output power of a power supply is supplied, the code modulation circuit modulating the output power of the power supply to generate a code-modulated wave by code modulation using a modulation code based on a code sequence, and transmitting the code-modulated wave to the code demodulator via the transmission path; and a control circuit that controls the code modulation circuit. The control circuit sets a frequency of the modulation code to a multiple of an output power frequency of the power supply.

Abstract: The power transmitter apparatus is provided with code modulators which modulate powers of phase components of three-phase alternating-current power to generate code-modulated waves, respectively, by code modulation using modulation codes based on code sequences different from each other, and transmits the code-modulated waves to the at least one power receiver apparatus via the transmission path. The power receiver apparatus is provided with code demodulators, each of which demodulates one code-modulated wave of the received code-modulated waves to generate code-demodulated power by code demodulation using a demodulation code based on a code sequence identical to the code sequence of the modulation code used for the code modulation of the one code-modulated wave, the code-demodulated power being generated as power of one of phase components of multiphase alternating-current power.
