Power Density — educational diagram — Fig.: Diagrama educativo de “Power Density”.

Power density is deliverable power per unit volume or area — critical when AGV belly clearance is tight and floor pads must survive forklift traffic. Higher density comes from better devices, higher frequency, improved magnetics, and integrated cooling — each with cost and complexity.

Marketing kW per square meter means little without stating gap, misalignment, coolant, and ambient.

01Levers

Wide bandgap switches and optimized magnetics for smaller tanks.
Higher frequency with Litz and careful AC loss control.
Liquid or directed airflow in pedestals; heat spreading in floor assemblies.
Multi-coil arrays with selective excitation for localized power delivery.

02Limits

EMI and safety clearances do not shrink with silicon scaling. Human-accessible surfaces have temperature and field exposure limits. Receiver volume on AMRs competes with battery and structure — density pushes against service access.

03Specification discipline

Quote power density at worst-case alignment and ambient.
Include inverter, coil, and rectifier loss in density figures, not coil alone.
Document maintenance clearance for dense assemblies.
