Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a fixed switching pattern is used to increase electric power conversion efficiency, then conversion efficiency is improved, but switching element temperature increases excessively
Solution Approach 1:
The patent implements dynamic switching pattern selection by introducing a determination device that monitors system conditions and selects between multiple switching patterns (first pattern for efficiency, second pattern for temperature control) based on real-time load conditions and temperature states, transforming the static switching approach into a dynamic adaptive system
Solution Approach 2:
The patent changes the switching pattern parameter based on operating conditions. The control device switches between different switching patterns (first pattern prioritizing efficiency, second pattern prioritizing temperature suppression) according to determination results from the determining device, effectively changing system parameters to resolve the contradiction
2Loss of energy
If a fixed switching pattern is used to prioritize conversion efficiency, then efficiency is improved, but adaptability to different operating conditions deteriorates
Solution Approach 1:
The system transitions from a static fixed switching pattern to a dynamic adaptive system where the determining device continuously monitors load conditions and temperature states, and the control device adjusts the switching pattern accordingly, enabling the system to adapt to varying operating conditions while maintaining efficiency
Solution Approach 2:
The patent creates a multi-functional switching control system that can perform multiple functions: efficiency optimization under normal conditions, temperature suppression under high-temperature conditions, and adaptive adjustment under varying load conditions. The switching pattern selection mechanism provides universal applicability across different operating scenarios

AI summary
An electric source control apparatus has: a determining device for determining whether a converter operates in a first mode or a second mode, wherein the first mode prioritizes increase of efficiency of the electric power conversion than the second mode does and the second mode prioritizes suppression of increase of element temperature of the switching element than the first mode does; and a controlling device for controlling the converter so that (i) a switching pattern becomes a first pattern, if the converter operates in the first mode and (ii) the switching pattern becomes a second pattern, if the converter operates in the second mode, wherein the first pattern is capable of increasing the efficiency of the electric power conversion more than the second pattern is and the second pattern is capable of suppressing the increase of the element temperature more than the first pattern is.
