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 …

Why it's free to use
- Filed May 31, 1996 and granted September 26, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 31, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 31, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
