Loss Breakdown Analysis — educational diagram — Fig.: Diagrama educativo de “Loss Breakdown Analysis”.

Loss breakdown analysis assigns watts to each subsystem so improvement efforts target the largest contributors. Methods include calorimetry, electrical calculation from measured waveforms, and incremental substitution of known-efficient components.

Without breakdown, teams over-optimize switching loss while conduction loss dominates at fleet operating point.

01Categories

PFC and input filter loss.
Inverter switching and conduction loss.
Coil copper and ferrite core loss.
Receiver rectifier or SR loss.
Control and auxiliary supply overhead.

02Process

Measure at nominal and worst-case alignment. Use thermal camera to cross-check calculated device loss. Document assumptions for magnetics loss when direct measurement is impractical.

03Action

Prioritize redesign where marginal improvement times fleet kWh is largest.
Track breakdown revision to revision in product change records.
