Power Factor
The purpose of this Tech Note is to clear up a common misunderstanding about the measurement of power in alternating current (AC) circuits. Most people with electrical experience have heard that power equals amps times volts. This is always true for direct current (DC) circuits, but the situation

IR Drop Compensation Adjustment
Although a typical DC motor presents a mostly inductive load, there is always a small amount of fixed resistance in the armature circuit. The armature, intercoil, series field, brushes, wiring between motor and controller, etc., comprise the armature circuit resistance. Typical resistance values

Comparing Methods to Determine the Health of Battery Systems (.pdf)
There have been many papers written about methods used to determine the health of batteries in critical standby applications. This paper intends to produce a critical analysis of the various AC "impedance" and DC "resistance" or "voltage response" measurement methods used in both portable (off-line
