Understand how to evaluate and optimize power supply efficiency without getting lost in equations. This video explains:
• Why higher efficiency reduces losses, heat, and environmental impact
• Relationship between efficiency and internal power dissipation (conceptual view)
• Practical measurement setups for DC/DC and AC/DC converters
• Importance of measuring voltages directly at the converter pins to avoid wiring errors
• How to read efficiency curves versus input voltage and load percentage
• Influence of input range, load level, and ambient temperature on performance
• Role of derating conditions (e.g. nominal voltage, full load, standard ambient)
• Hidden system losses: wiring, PCB traces, connectors, fuses, EMI filters, diodes
• Designing for system-level, not just headline efficiency
