Abstract
A power supply for supplying the heating coils of a tube (WR), in particular a traveling-wave tube, wherein a transformer (Tr) and an inverter (S1, S2) are provided in the heating circuit of the tube (WR), and the frequency of the AC current is reduced from a high initial value to a lower value during the heat-up time of the tube (WR) in such a way that the change of the inductive voltage drop caused by this frequency change limits the heating current at the leakage inductance (LS) of the transformer (Tr).
