Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power transmission systems face inefficiencies in transmitting power due to long-distance transmission losses and the need for synchronized code modulation and demodulation to maintain high transmission efficiency.
Innovation Solution
A power transmission system that includes a code modulator and a code demodulator, which convert first AC power into code-modulated power and then back into second AC power with a lower frequency, using conversion codes to synchronize and adjust the power transmission, allowing for efficient power transmission across multiple generators and loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If power is transmitted over long distances, then power can be supplied to distant loads, but transmission losses increase
Solution Approach 1:
The patent applies periodic action by using code-modulated power with alternating current that periodically reverses direction. The modulation code creates a periodic waveform that enables efficient power transmission through the transmission path, reducing losses compared to continuous direct current transmission over long distances.
Solution Approach 2:
The patent changes the frequency parameter of the power transmission by generating second AC power with a lower frequency than the first AC power. This frequency transformation optimizes transmission efficiency and reduces losses in the transmission path while maintaining power delivery capability.
2Productivity
If code modulation and demodulation are synchronized, then transmission efficiency is maintained, but system complexity increases
Solution Approach 1:
The patent implements feedback by having the code demodulator use a conversion code generated based on the modulation code received from the code modulator. This feedback mechanism ensures synchronized operation between modulation and demodulation, maintaining transmission efficiency while managing system complexity through coordinated code generation.
Solution Approach 2:
The conversion code acts as an intermediary between the modulation code and the demodulation process. It is generated based on the modulation code and used by the code demodulator to properly reconstruct the power signal, facilitating synchronized operation without requiring direct complex communication between modulator and demodulator.
3Loss of energy
If frequency is reduced in power conversion, then transmission efficiency improves, but power conversion complexity increases
Solution Approach 1:
The patent merges the frequency conversion function into the code modulation/demodulation process itself. The circuit that converts code-modulated power to generate second AC power with lower frequency integrates frequency transformation with power conversion, reducing the need for separate frequency conversion stages and simplifying the overall system.
Solution Approach 2:
The code modulator and code demodulator perform multiple functions simultaneously: they modulate/demodulate the power signal, convert frequency, and manage synchronization. This multi-functionality reduces the need for separate dedicated circuits for each function, lowering overall system complexity while achieving frequency reduction for improved transmission efficiency.

AI summary
A converter includes: a terminal that receives code-modulated power into which first alternating-current power has been code-modulated with a modulation code; and a circuit that converts the code-modulated power with a conversion code to generate second alternating-current power. The conversion code is based on the modulation code. A frequency of the second alternating-current power is lower than a frequency of the first alternating-current power.
