HIGH PULSE RATE PULSE POWER SYSTEM WITH LIQUID COOLING

摘要

A high pulse rate pulse power source (20) for supplying controlled high energy electrical pulses at rates of 2000 Hz or greater. The source (20) includes a pulse generating circuit (50) including a charging capacitor (42), a solid state switch (44-46) and a current limiting inductor (48). Pulses generated in the pulse generating circuit (50) are compressed in at least two pulse compression circuits and a step-up pulse transformer increases peak voltage to at least 12,000 volts. A very fast regulated power supply is provided for charging the charging capacitor (42) in less than 400 microseconds and a pulse control system including a programmed processor (102) controls the charging of the charging capacitor (42) an accuracy of less than about one percent at a rate of at least 4000 charges per second. In a preferred embodiment capable of operating at pulse rates of 2000 to 4000 Hz or greater, water cooling of the saturable inductors (48, 54, 64) is provided.
