Patent ID: 7514819

Claim:
A pulse power apparatus for generating a pulse through an electrical load, said apparatus comprising: a charging power supply; a plurality of pulse power supply modules connected in parallel to each other, each of said plurality of pulse power supply modules including: at least one capacitor for storing an electrical energy supplied by said charging power supply, said at least one capacitor electrically connected to said electrical load and said charging power supply; and a semiconductor switch assembly having an input coupled to said at least one capacitor for allowing said stored electrical energy to be transferred from said at least one capacitor to said electrical load for generating said pulse through said electrical load, said semiconductor switch assembly including a semiconductor switch controlled by a pulse generator, said semiconductor switch allowing current reversal therethrough to said at least one capacitor in order to extend duration of application of said electrical energy though said electrical load; and an electronic control module operatively coupled to said semiconductor switch and said pulse generator of said semiconductor switch assembly of each of said plurality of pulse power supply modules for independently and selectively controlling said plurality of pulse power supply modules in order to selectively transfer said stored electrical energy from said capacitors to said electrical load for a fixed period of time.
