A pulse forming network (PFN) accumulates electrical energy over a comparatively long time, then releases the stored energy in the form of a relatively square pulse of comparatively short duration for various pulsed power applications. In practice, a PFN is charged by means of a high voltage power source, then rapidly discharged into a load via a high voltage switch, such as a spark gap or hydrogen thyratron. The load may be a high power microwave oscillator such as a klystron or magnetron, a flashtube, or even an electromagnet. Depending upon the application, the output pulse repetition rate may range from a fraction of a Hertz to over 10kHz.

Famous quotes containing the words pulse, forming and/or network:
“Whoever has had the experience of the moral sentiment cannot choose but believe in unlimited power. Each pulse from that heart is an oath from the Most High. I know not what the word sublime means, if it be not the intimations, in this infant, of a terrific force.”
—Ralph Waldo Emerson (1803–1882)
“Piety is the fermentation of the forming mind and the putrefaction of the disintegrating one.”
—Franz Grillparzer (1791–1872)
“Parents need all the help they can get. The strongest as well as the most fragile family requires a vital network of social supports.”
—Bernice Weissbourd (20th century)
