Multi-bridge topology power supply dynamic reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems are limited in their ability to dynamically adjust and switch between different bridge topologies during operation, restricting their flexibility in providing varying power levels and resonant frequencies.
Innovation Solution
A multi-bridge topology power supply system that includes multiple half-bridge circuits connected to a controller, allowing the system to selectively configure between various bridge topologies by controlling the switches and capacitive configurations, enabling switching between full bridge, half bridge, and other topologies with capacitive dividers, while maintaining a constant resonant frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed bridge topology is used, then the circuit design is simple, but the power supply cannot dynamically adjust power levels or resonant frequencies
Solution Approach 1:
The power supply is divided into multiple independent half-bridge circuits (first half-bridge circuit and second half-bridge circuit) that can be selectively activated. Each half-bridge circuit contains its own switches and capacitors, allowing independent control to achieve different topology configurations without requiring complete circuit redesign.
Solution Approach 2:
The system transitions from a static fixed topology to a dynamic reconfigurable topology by using controller-driven switches that can change the circuit configuration in real-time. The controller selectively activates different half-bridge circuits and controls switch timing to adapt the bridge topology according to power level requirements.
2Adaptability or versatility
If multiple separate power supplies are used to cover different power ranges, then each power supply can be optimized for its range, but the overall system cost and complexity increase
Solution Approach 1:
A single power supply system is designed to perform multiple functions by covering different power ranges through topology switching. The same physical hardware (half-bridge circuits, capacitors, inductors) serves multiple purposes by being reconfigured via controller logic, eliminating the need for separate power supplies for different power levels.
Solution Approach 2:
Multiple half-bridge circuits are merged into a single integrated system that can operate in different configurations. By combining the functionality of what would traditionally require separate power supplies into one unified reconfigurable system, component count is reduced while maintaining full power range coverage.
3Productivity
If the bridge topology is changed during operation, then power levels can be adjusted quickly, but additional components and reconfiguration mechanisms are required
Solution Approach 1:
The system enables dynamic power adjustment by allowing real-time switching between different bridge topologies through controller-managed switch operations. This dynamic reconfiguration allows rapid transition between power levels without mechanical moving parts or complex external reconfiguration mechanisms.
Solution Approach 2:
The controller automatically manages the topology switching and power level adjustment without requiring external intervention or complex manual reconfiguration. The system self-adapts by having the controller monitor power requirements and selectively activate appropriate half-bridge circuits and switch combinations.
