Definitions

the high-voltage generator is intended for supplying one or possibly several loads of the unidirectional type such as, for example, a magnetron of a microwave oven or an electronic tube, and comprises a voltage-boosting transformer.
a primary stage E- ⁇ connected to a primary circuit and a secondary stage E 2 having a winding L 3 connected to a secondary circuit s 0 ' s ⁇ comprising the load of use, said primary circuit connecting the primary stage E ⁇ of the transformer T to a source of electrical energy B Q , B- * L and comprising switching means K so as to supply the transformer T with high frequency current.
