Modular Power Supply Noise Reduction via Isolation Transformer

The patent introduces an isolation transformer as an intermediary component between power supply modules connected in parallel. The transformer provides galvanic isolation, blocking the propagation of noise and cross-talk between modules while allowing power transfer. This resolves the contradiction by enabling parallel connection for higher power output while preventing noise interference through the isolating effect of the transformer.

The patent implements a self-service load sharing mechanism where each power supply module autonomously senses the output voltage and automatically adjusts its own output current contribution. Modules with higher output voltage naturally supply more current, while those with lower voltage supply less, achieving balanced load distribution without complex centralized control. This resolves the contradiction by maintaining simplicity while improving reliability through automatic self-regulation.

The patent segments the power supply system into electrically isolated modules, each capable of operating independently with different input voltage ranges. The isolation transformer prevents voltage reference conflicts between modules while maintaining stable operation. Each module's stability is preserved through segmentation, allowing the overall system to achieve high adaptability to different input conditions.
