Power supply unit with a pulse width modulated inverter, in particular for an X-ray generator

The power supply unit has a high short-term power in a first mode and a lower continuous power in a second mode. A static converter (1,2) is connected to a d.c. source (4) on the input side. The output of the static converter is connected to a capacitor (Cr) and the primary winding (Np) of a transfo...

description	The power supply unit has a high short-term power in a first mode and a lower continuous power in a second mode. A static converter (1,2) is connected to a d.c. source (4) on the input side. The output of the static converter is connected to a capacitor (Cr) and the primary winding (Np) of a transformer (Tr). The transformers secondary winding (Ns) is coupled to a rectifier (D11-D14). There is an arrangement for switching between the two operating modes. In the first mode a series circuit containing the primary winding and the capacitor is connected to the static converter output. In the second mode a series circuit containing an inductance (Lh) in series with the primary winding and capacitor is switched in.
