Abstract: A high voltage transformer module (50) having a pair of high voltage substrates (64, 66) and a pair of low voltage substrates (62, 68) on which high and low voltage components are respectfully mounted. Mounted between the substrates are a plurality of transformers (92a, 92b, . . . 92n). In a preferred embodiment, each of the plurality of transformers is coupled to a full bridge rectifier (102a, 102b, . . . 102n) and the outputs of the rectifiers connected so that an output voltage produced by each transformer/rectifier pair is summed to produce a total output voltage for the high voltage transformer module. Electrical shorts are prevented within the module by fixedly mounting the substrates in the casing and by filling the cavities formed between the substrates with insulation having a high breakdown voltage. The components on the high voltage substrates are both physically and electrically isolated from the components on the low voltage substrates.

Abstract: A high voltage power supply (40) having a plurality of high voltage generators (50a, 50b, . . . 50j) that produce a controlled current in a load (24) having a capacitive component. Each high voltage generator consists of a pulsewidth-modulated (PWM) inverter, a high voltage transformer, and a high voltage full bridge rectifier. The high voltage generators are divided into three groups: Group I, Group II, and Group III. During a driving mode of power supply operation, the Group I, Group II, and Group III high voltage generators produce an output voltage (V.sub.gen) from the power supply which exceeds a voltage (V.sub.c) across the capacitive component of the load, causing the current in the load to increase. When the current in the load reaches a desired value, the power supply enters a tracking mode of operation. During the tracking mode, the Group I and Group II high voltage generators produce an output voltage (V.sub.gen) from the power supply which equals the voltage (V.sub.
