PCS Efficiency Curves: The Hidden Trap in Light-Load Operation
1. Rated Efficiency vs Real Efficiency
Most PCS datasheets highlight peak efficiency at rated power. In reality, many systems operate at partial load for most of their life.
2. Why Light-Load Performance Matters
Losses at low power accumulate over thousands of operating hours, directly impacting:
-
Annual energy throughput
-
Thermal aging
-
Operating cost
3. Engineering Evaluation
Engineers evaluate efficiency curves, not single numbers. Stable performance across a wide power range is more valuable than a high peak value.

4. Conclusion
True efficiency is defined by how the system operates most of the time, not at its limits.
