Abstract

A plurality of modules, each adapted to generate repetitive RF pulses are connected to a common coarse DC power supply. Each of the modules, which include a pulsed load, has a switching transistor connected in series with the load, and a precise voltage connected to its base to regulate the voltage during each of the individual pulses. A capacitor may be connected in each of the modules for improving the rise time of the individual pulses.

Claims

1. A distributed pulsed power supply, comprising

a direct current power supply,

a plurality of modules, each having a pair of inputs electrically connecting each said module in parallel to said power supply,

a switching transistor having collector, emitter and base portions mounted within each of said modules, said collector portion being connected electrically to one of said inputs,

a pulsed load mounted in each said module electrically connected at one side to the emitter portion of its respective switching transistor and at its other side to the other of the pair of inputs, said pulsed load including means to repetitively open and close a circuit path from the power supply through the collector and emitter portion of its switching transistor,

a precision voltage source for each module connected electrically to the base portion of its respective switching transistor, said precision voltage being a value to produce a current substantially equal to the load requirements of its module divided by the current gain of the switching transistor, said switching transistor being operative in a linear regulator mode.

2. A power supply according to claim 1 further including a capacitor mounted in the module electrically connected to the collector portion of the switching transistor at its one side and to the other of the pair of inputs at its other side.

3. A power supply according to claim 1 or 2, wherein the distance between the emitter portion and the load means is less than approximately two inches.

4. A power supply according to claim 1, 2 or 3 wherein the precision voltage source has an output stage and the distance between the base portion and the precision voltage source is less than approximately two inches.

5. A power supply according to claim 1, wherein said pulsed load includes at least an inductor and an RF transistor connected in series, with said series connection being electrically connected across the emitter portion of the switching transistor and the DC power supply.
