Abstract
A high-voltage generator, includes a rectifier circuit (9) and a measuring resistor arrangement (8) for forming a measuring voltage (U.sub.M) which is proportional to the direct voltage (U.sub.DC), the measuring resistor arrangement (8) comprising at least one associated measuring resistor (R.sub.1, R.sub.2, R.sub.3) for each rectifier stage (31, 32, 33). In order to achieve a cost-saving and notably space-saving construction with adequate shielding of the measuring resistors (R.sub.1, R.sub.2, R.sub.3) from parts of the circuit (C.sub.4 . . . C.sub.9, 1, 2, 3) carrying the alternating voltage and from ground potential, the measuring resistors (R.sub.1, R.sub.2, R.sub.3) are integrated in the associated rectifier stages (31, 32, 33) and enclosed by a shield (11, 12, 13) which carries the direct voltage potential of the associated rectifier stage (31, 32, 33).
