Switchgear Cabinet Cooling With Wide-Range AC to DC Power

The patent implements a universal voltage supply architecture where a single transformer variant with wide-range primary winding connections can accept multiple input voltages (115V, 230V, 400V), and a single controller variant operates across all voltage conditions. This eliminates the need for multiple specialized transformer and controller variants, reducing device complexity while maintaining global adaptability.

The patent employs parameter changes by allowing the transformer's primary winding connections to be reconfigured for different voltage inputs, and the controller's operating parameters to be adjusted based on detected input voltage. This enables a single hardware design to adapt to different voltage conditions through parameter modification rather than requiring multiple hardware variants.

The patent designs cooling device components, particularly the controller and transformer, as universal units that can operate with multiple input voltages. This allows a single production line to manufacture components for all voltage regions, eliminating the need for separate production lines for 115V, 230V, and 400V variants, thereby simplifying manufacturing and reducing costs.

The patent segments the voltage adaptation function into a modular transformer design with reconfigurable primary windings and a controller with voltage detection and adaptation capabilities. This modular segmentation allows the core components to be produced in standard configurations while maintaining flexibility for different voltage inputs, simplifying the manufacturing process.

The patent introduces a transformer as an intermediary device that converts various input voltages (115V, 230V, 400V) to a standardized secondary voltage that the controller and cooling components can universally accept. This intermediary transformation enables a single variant device to operate across different voltage regions without requiring the controller or cooling components to directly handle multiple voltage inputs.

The controller incorporates voltage detection and automatic adaptation capabilities, allowing it to self-configure based on the detected input voltage. This self-service feature enables the single variant device to automatically adjust to different voltage conditions without requiring manual configuration or multiple specialized variants, maintaining low device complexity while ensuring broad voltage compatibility.
