Coupled Inductor Resonance Tuning for Power Amplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupled inductors primarily rely on the magnetic field for voltage induction in secondary windings, limiting the scope of power amplification.
Innovation Solution
The system generates a linear magnetic wave in addition to the traditional magnetic field, by adjusting the pulse frequency to approach the harmonic frequency of the magnetic core, thereby amplifying power output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If only the magnetic field is used for voltage induction in secondary windings, then the system is simple to operate, but the power amplification is limited
Solution Approach 1:
The patent applies mechanical vibration principles by generating linear magnetic waves through pulsed DC current that oscillates at or near the natural resonant frequency of the magnetic core. This vibrational approach creates standing waves within the core, producing counter electromotive force that amplifies power output beyond what traditional magnetic field induction alone can achieve
Solution Approach 2:
The patent changes the operational parameters by using pulsed DC current instead of traditional AC, and by tuning the pulse frequency to match the harmonic frequency of the magnetic core. This parameter adjustment transforms the magnetic core into a resonant system that generates amplified counter electromotive force, resolving the contradiction between simplicity and power amplification
2Power
If DC pulse frequency is increased to approach harmonic frequency of the core, then power output is amplified, but the system becomes more sensitive to frequency tuning
Solution Approach 1:
The patent employs feedback mechanisms where the counter electromotive force generated by the linear magnetic wave feeds back into the system, reinforcing the oscillations at the resonant frequency. This feedback effect creates a self-sustaining oscillation that is relatively tolerant to frequency variations, reducing the sensitivity to precise frequency tuning while maintaining power amplification
3Power
If linear magnetic wave is generated in addition to magnetic field, then power amplification increases, but the device complexity increases
Solution Approach 1:
The patent makes the magnetic core serve multiple functions: it acts as both the traditional magnetic coupling medium and as a resonant oscillator that generates linear magnetic waves. This multi-functionality allows the same component to provide both magnetic field induction and wave-based counter electromotive force, achieving power amplification without adding separate dedicated components
Solution Approach 2:
The patent uses periodic pulsed DC current to generate the linear magnetic wave, replacing continuous AC with periodic pulses. This periodic action creates discrete oscillations that build up resonance in the magnetic core, generating the counter electromotive force needed for power amplification while using the same basic inductor structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach results in a proportional increase in power output, amplifying power to several times higher than the input power by combining counter electromotive force from both magnetic waves.
Implementation Method 1
a voltage is induced in one coil by the changing magnetic field generated by the current flowing in the other coil. The process of generating a magnetic field and inducing a current in the other coil is known as mutual inductance and is described by Faraday's law of induction.
Implementation Method 2
Direct current (DC) pulses create a time-varying magnetic field that induces a magnetic field that is radically different than the smooth sine wave produced by an alternating current (AC) wave.
Implementation Method 3
The linear magnetic wave is generated as the pulse frequency approaches the harmonic frequency of the core.
