Power supply device regulated a passive circuit, in particular for a travelling wave tube.

摘要

The regulated supply device comprises regulation means (MR), comprising an inductive circuit (L) and a resistive circuit (R) which are connected in parallel, connected between an input (BE1) intended to be connected to a substantially DC high-voltage source (SO), and an output (BS) capable of supplying the cathode (K) of a UHF tube (TOP) with voltage, which tube is capable of emission by pulses, generating corresponding pulse current demands. The level of the input voltage at low or zero current and the characteristics of the regulation means are designed, in view of the time-domain characteristics of the pulses, to deliver, in the presence of the said current demands, a regulated output voltage of substantially constant level and equal to a rated level chosen as a function of the characteristics of the tubes and allowing the emission of the said pulses.
