Abstract
Abstract A compact high voltage power supply includes a high voltage transformer 4 with individual concentric secondaries S1, S2, . . . , connected to form a ladder network with two series-connected assemblies of diode rectifiers R and R' respectively located on corresponding sides of the transformer winding. Next-adjacent secondaries S1, S2, . . . , are wound from the same side of the winding space but in an opposite winding sense, and each secondary comprises an odd plurality of layers. This provides a high voltage transformer arrangement without cross-connection of the diodes in which the peak and alternating voltages across the interwinding insulation is optimally reduced and the smoothing effect of stray capacitances is enhanced.
