Title: Push-pull direct voltage converter - with impulse width control of primary current to provide output voltage regulation
Inventor: PIVIT ERICH DR ING
IPC: H02M3/337
Filed: 1979-01-20
Abstract: The voltage converter is principally employed for producing a high voltage output for use with a travelling wave tube. The transformer (T) has a centre tapped primary winding (W1) whose ends are connected via switches (S1, S2) to a choke (L) and to one pole of the dc supply (Uo). The other pole is connected to the centre tap. The switches, typically transistors, are controlled by a square wave oscillator to give a variable overlap time during which both are conducting. This variation is used to control the output voltage of the secondary winding (W 2, U1'). In order to avoid insulation problems on the transformer a voltage multiplier circuit (SVVe may be connected to the secondary winding to produce the required high output voltage (U1"). The choke (L) may be incorporated in the transformer by making the latter with a high leakage.
