Engineering Contradiction Analysis
1Adaptability or versatility
If additional magnetic components, multiple windings, or additional switching/linear regulators are used to generate multiple voltages, then voltage generation capability is improved, but device complexity, cost, and size increase
Solution Approach 1:
The patent applies multi-functionality by enabling a single switching converter circuit to generate multiple voltage outputs (first voltage and second voltage) through selective capacitor charging. The same switching stage and capacitors serve dual purposes: generating the main voltage and deriving auxiliary voltages by controlling which capacitors are charged during switching cycles, eliminating the need for separate voltage generation circuits.
Solution Approach 2:
The patent merges multiple voltage generation functions into a single integrated switching converter circuit. Instead of using separate magnetic components and regulators for each voltage, the invention combines all voltage generation functions into one circuit that uses a common switching stage, capacitors, and control logic to produce multiple voltages simultaneously.

AI summary
An electronic converter comprising a switching stage having at least one electronic switch, wherein the switching stage is configured to provide current pulses via a terminal; a first capacitor, wherein the first capacitor provides a first voltage. Specifically, the electronic converter further includes a second capacitor to provide a second voltage, comparison means configured to detect the difference between the first voltage and the second voltage, and determine a comparison signal which indicates whether this difference is greater than a threshold, and switching means configured to selectively transfer the current to the first capacitor or the second capacitor as a function of the comparison signal. The switching means may include a SCR, where the anode of the SCR is connected to the terminal that provides current pulses and where the cathode of the SCR is connected to the second capacitor.
