1Productivity
If electrical resonance is utilized to increase power capture ratio, then power conversion efficiency is improved, but traditional generators and electric power components may be damaged due to high voltages and high reactive power
Solution Approach 1:
The patent converts the harmful high reactive power generated during electrical resonance into beneficial active power through a bridge circuit with semiconductor switches. The circuit redirects the reactive power flow to perform useful work, transforming what would normally be a damaging effect into a source of additional power output.
Solution Approach 2:
The patent changes the electrical parameters of the system by introducing a bridge circuit that dynamically adjusts the flow of reactive power. By controlling semiconductor switches, the system modifies the electrical characteristics to allow resonance conditions while preventing damage through parameter transformation and redirection.
2Productivity
If mechanical resonance design is optimized to coincide with wave frequency, then power capture ratio is maximized, but the system design becomes very complicated due to multiple parameters and requirements
Solution Approach 1:
The patent replaces complex mechanical resonance design with an electrical resonance solution. Instead of optimizing mechanical components to achieve resonance with wave frequency, the invention uses an electrical bridge circuit with capacitors and semiconductor switches to create electrical resonance, thereby achieving the same power capture ratio improvement without mechanical design complexity.
3Reliability
If electrical resonance is avoided in traditional electrical systems, then generators and power components are protected from damage, but power conversion efficiency is limited
Solution Approach 1:
The patent introduces a bridge circuit with semiconductor switches as an intermediary between the generator and the load. This intermediary component manages the reactive power flow during resonance conditions, protecting the generator while enabling efficient power transfer to the load through controlled switching and power factor correction.
