Parallel Boost Converter Modules for Thin Device Current
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for larger output current in boost converters leads to a larger inductor size, making it difficult to maintain the thickness of electronic devices, which becomes a challenge in the design of compact and thin electronic devices.
Innovation Solution
A boost converter circuit design that includes multiple boost modules connected in parallel, each with a detecting unit that adjusts input signals for a comparing control unit, allowing for increased output current without increasing inductance, thereby reducing the thickness of the electronic device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the inductance of the inductor is increased to provide larger output current, then the output current capability is improved, but the height and size of the inductor increase, making it difficult to maintain thin device profile
Solution Approach 1:
The patent divides the single inductor into multiple smaller inductors (first inductor and second inductor) connected in parallel. Each inductor handles a portion of the total current, allowing the device to achieve high output current capability without requiring any single inductor to be tall or large. This segmentation resolves the contradiction by distributing the current burden across multiple compact components.
2Productivity
If multiple boost modules are connected in parallel to increase output current, then the output current capability is improved, but the circuit complexity increases
Solution Approach 1:
The patent combines multiple boost modules into a single integrated circuit structure where the modules share common components such as the output capacitor and control logic. The detecting units and comparing control units are implemented in an integrated manner, allowing parallel operation of multiple inductors while maintaining a compact, unified circuit design that does not proportionally increase overall complexity.
