Abstract
A novel and economical transformer is described for use in a static inverter in association with one or two switching devices, typically transistors. The transformer produces an output for control of the associated switching device(s) which changes in sense as a function of the flux level in the transformer core. The arrangement is applicable to a figure '8' flux configuration such as is achieved from two 'E' cores, and requires only a single aperture located at the base of the common branch. Control is effected by a single primary and single secondary winding wound through the aperture. With two switching devices, two apertures are normally provided. The core which supports a figure '8' flux configuration may take other more economical alternatives such as 'I' core, 'T' core or a single 'E' core.
