Compensated pulsed alternator

A compensated pulsed alternator, also known by the portmanteau compulsator, is a form of power supply. As the name suggests, it is an alternator that is "compensated" (see below) to make it better at delivering pulses of electrical energy than a normal alternator. Description and operation The principle is very similar to an alternator, except the rotor is usually kept spinning by its inertia (having been "spun up" by an external motor, or the compulsator itself having been used in reverse as an AC motor) and the small matter of the "compensation". The compulsator is used like a capacitor, to gather energy from a low-power source and store it, then generate a high-power output for a short period.
