Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power transmission systems are limited in their ability to transmit power from multiple power supplies to multiple loads via a common path, especially when dealing with different types of power supplies and loads, such as direct current, single-phase alternating current, and multiphase alternating current, and require a large number of power transmission cables, increasing costs and complexity.
Innovation Solution
A power transmitter apparatus that uses code modulators to modulate the phase components of multiphase alternating-current power and transmit code-modulated waves to a power receiver apparatus via a transmission path, allowing for the transmission of power across different types of power supplies and loads using code modulation and demodulation techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional power transmission systems use separate transmission paths for different types of power supplies and loads, then power transmission reliability is improved, but system complexity and cost increase due to requiring a large number of transmission cables
Solution Approach 1:
The patent combines multiple transmission paths for different power types (DC, single-phase AC, multiphase AC) into a single shared transmission path. By using code modulation techniques, the system can transmit and distinguish different power components through the same physical medium, thereby reducing the number of required cables and system complexity while maintaining reliable power transmission between different power supply and load types
2Adaptability or versatility
If conventional power transmission systems support multiple types of power supplies and loads, then system versatility is improved, but the requirement for multiple dedicated transmission paths increases device complexity
Solution Approach 1:
The patent creates a universal transmission path that can handle multiple power types (DC, single-phase AC, multiphase AC) simultaneously. The code modulation system allows the same transmission infrastructure to serve different power supply and load combinations, making the system highly versatile without requiring dedicated paths for each power type combination
3Measurement precision
If conventional power transmission systems use separate transmission paths for each power component, then power component distinction is improved, but transmission cost and system complexity increase
Solution Approach 1:
The patent introduces code modulation as an intermediary mechanism that enables precise distinction of different power components through a single transmission path. By encoding power components with unique code sequences, the system achieves accurate identification and separation of power sources at the receiving end, eliminating the need for multiple physical transmission paths while maintaining clear power component distinction

AI summary
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.
