Pulse<br />

In the design of a permanent magnet / pulsed<br />

dc electromagnet motor-generator, the creation<br />

of a high power pulse at the optimum time, when<br />

the permanent magnet and electromagnet are<br />

slightly past alignment, is the goal. The use of<br />

power is confined to a brief, few milliseconds<br />

thus conserving power and increasing efficiency.<br />

In order to create a high power pulse at the<br />

optimum time, it is helpful to analyze transient<br />

currents and transient voltages.<br />

A transient current effect is associated with<br />

sudden changes in voltage when an emf is first<br />

applied. A transient current is developed when<br />

a switch is turned on. In this condition, the<br />

power is off in the circuit and then the switch is<br />

closed. At this point in time, power, being<br />

current and voltage being to flow in the circuit,<br />

but at different rates. When the switch is first<br />

closed there is an immediate surge in current<br />

which decreases exponentially over time to a<br />

steady state current. The voltage, on the other<br />

hand starts at zero and increases exponentially<br />

to a steady state condition.<br />

The transient current effect is significant in<br />

two conditions, when a capacitor is employed<br />

in a basic RC circuit and when a high-voltage<br />

spark gap, exposed to open air creates an<br />

avalanche of free electrons.<br />

Let us examine a series circuit with a capacitor<br />

and resistor. In a simple RC circuit the<br />

exponential change in current and voltage occur<br />

during a period of five time constants. As the<br />

switch is closed, one half of the current stored<br />

on the negative plate of the capacitor surges into<br />

the conducting circuit during the first time<br />

constant. The initial value of the current is<br />

determined by the voltage of the capacitor and<br />

the resistance in the circuit. The amount of<br />

transient current is directly proportional to the<br />

voltage and inversely proportional to the<br />

resistance. The less the resistance, the greater<br />

the initial current. This high current pulse or<br />

transient current can be of a much higher value<br />

than the normal allowable current rating for the<br />

wire size. This is because the duty cycle, time<br />

on / time off, allows the wire to cool in between<br />

pulses. This is important because the strength<br />

of the inductive pulse is determined by the<br />

amperage and the number of turns on the<br />

electromagnet.<br />

Simple stated, the charge on the capacitor<br />

provides a powerful pulse of current to the<br />

electromagnet when the switch is first closed.<br />

This high current pulse forms a very strong<br />

magnetic flux in the turns of the electromagnet.<br />

The transient current provides an inductive<br />

kick to forcefully repell the permanent magnet<br />

and electromagnet. An other condition where<br />

a transient current is developed is by the means<br />

of avalanche due to the ionization of air<br />

molecules in a high-voltage spark gap exposed<br />

to open air. It is sufficient to say that with a<br />

spark gap exposed to open air of 4 mm at 5,000<br />

vdc the process of avalanche produces some<br />

5,000 free electrons that are absorbed by the<br />

high voltage anode into the circuit for every<br />

initial electron that leaves the cathode.<br />

Editorial note: Experiments to increase current in<br />

electrical circuit by means of air ionization were<br />

demonstrated also in 1996, New Ideas in Natural<br />

Sciences conference, St.Petersburg, Russia. This<br />

method was patented by Russian scientist<br />

P.Yablotchkov, 1877. Efficiency was about200%.<br />
