High voltage isolating transformer module
First Claim
1. A transformer module comprising:
- (a) a casing;
(b) a first substrate formed with a plurality of holes and mounted in said casing;
(c) a second substrate mounted in said casing;
(d) a support that maintains the second substrate at a distance from the first substrate;
(e) a plurality of transformer stages mounted on the first and second substrates, each of the plurality of transformer stages comprising;
(i) a core mounted on the second substrate, the core extending through the plurality of holes in the first substrate;
(ii) a primary winding surrounding the core; and
(iii) a secondary winding mounted on the first substrate, the secondary winding surrounding the core at a distance, wherein a current through the primary winding will induce a current through the secondary winding and generate a voltage across the transformer stage; and
(f) an insulating material surrounding the first substrate, the second substrate, and the plurality of transformer stages.

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.
