An electric circuit evaluation method that includes steps to find malfunction power frequency, current frequency, and voltage frequency properties by representing the magnitude of critical noise signals through power injection, current flow, and voltage measurements, allowing for the extraction of malfunction current and voltage frequency properties from power frequency data, which are then used to improve circuit design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If DPI test is used to find malfunction power frequency property, then the magnitude of critical noise signal can be represented by power injected into the designated electric circuit, but the information is difficult to treat for improving actual circuit design
Solution Approach 1:
The patent segments the malfunction analysis into three independent properties: power frequency property, current frequency property, and voltage frequency property. Each property is represented by different physical quantities (power, current, voltage) and can be analyzed separately to identify specific malfunction causes, thereby reducing information loss while maintaining measurement precision.
Solution Approach 2:
The patent introduces current frequency property and voltage frequency property as intermediary representations that bridge the gap between power frequency property and actual circuit malfunction causes. These intermediary properties provide additional insights into the malfunction mechanisms without requiring direct complex measurements, enabling better circuit design improvements.
2Ease of operation
If only malfunction power frequency property is measured, then the evaluation process is simple, but the causes of malfunctions cannot be accurately identified
Solution Approach 1:
The patent divides the malfunction evaluation into three separate property measurements (power, current, voltage), each providing specific insights into different aspects of the malfunction. This segmentation allows for accurate cause identification while maintaining operational simplicity through standardized measurement procedures for each property.
Solution Approach 2:
The patent adds two new dimensions to the evaluation: current frequency property and voltage frequency property, in addition to the existing power frequency property. This dimensional expansion enables accurate malfunction cause identification by providing multiple perspectives on the same malfunction phenomenon, without significantly increasing operational complexity.
3Measurement precision
If malfunction current and voltage frequency properties are added, then accurate malfunction cause identification is achieved, but the evaluation complexity increases
Solution Approach 1:
The patent creates a universal evaluation framework where power frequency property, current frequency property, and voltage frequency property can be measured using standard electrical measurement techniques. The same evaluation methodology can be applied to different circuit types and malfunction scenarios, providing accurate cause identification without requiring complex specialized equipment for each property.
Solution Approach 2:
The patent changes the representation parameters from single power measurement to multiple parameters (power, current, voltage) that can be measured using standard electrical instruments. By changing the parameter set rather than the measurement approach, the patent achieves accurate malfunction cause identification while minimizing the increase in evaluation complexity.
