Abstract
In a switching arrangement, a plurality of modules are connected such that the main switching elements, FETs, are in series. Control of and power to the FETs is supplied via a single turn primary passing through a plurality of toroidal secondary transformers. A train of control pulses is applied to the single turn primary and their polarity determines whether the main FET is switched on or off, the length of the pulse train determining the pulse width and PRF of the output of the switching arrangement. The control pulses are also used to supply power to the main driver of the main FET.
