|1. (WO2018128109) POWER TRANSMISSION SYSTEM|
|Applicants:||PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.
|Title:||POWER TRANSMISSION SYSTEM|
A power transmission device is provided with a plurality of code modulators (2A-1 to 2A-3) for respectively using a modulation code based on prescribed code sequences that differ from each other, code-modulating the power of each phase component of three-phase AC power that includes a plurality of phase components to respectively generate a code modulation wave, and respectively transmitting the code modulation wave through a transmission path to at least one power-receiving device. The power-receiving device is provided with a plurality of code demodulators (4A-1 to 4A-3) for respectively code-demodulating one code modulation wave from among the plurality of received code modulation waves using a demodulation code based on the same code sequence as the code sequence of the modulation code used when the one code modulation wave was code-modulated, and respectively generating the code-demodulated power as power for one phase component from among a plurality of phase components of polyphase AC power.
