AN4363 Application note Introduction

... Motor control applications A BEMF can be applied by a motor when the series AC switch is OFF. A motor can still be running due to inertia or if a mechanical torque is applied. A BEMF will occur across a motor if it is turning and if an inductive field is applied. This is the reason why, such a BEMF ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
