AI Technical Summary
Existing driver devices for building automation applications, particularly in lighting systems, face limitations in providing a desired load voltage range due to efficiency and switching frequency constraints, and they lack the capability to determine output power for each output channel without increasing circuit complexity and cost.
The driver device incorporates an isolation barrier using a transformer with multiple taps on the secondary winding to achieve multiple output voltage ranges, and it employs an evaluation circuit with an inductor and auxiliary winding to determine which load voltage range is in use without measuring current in each output channel individually.
This solution allows for determining the output power to each load and implementing individual switch-off capabilities for plural load output channels with increased accuracy, while maintaining a compact design and reduced complexity, thus addressing the limitations of existing technologies.
