Abstract
A transformer of a Tesla type, and energy supply and particle accelerator devices that include such transformers. The electrical transformer includes a primary winding, a secondary winding which is electromagnetically coupled to the primary winding, and is characterized in that the primary winding consists of one single turn. The transformer operates without any soft magnetic core. The single turn is formed by at least two sector segments of a rotationally symmetric body, over which segments a voltage is applied. Preferably, the segments are equal in size, the voltages are equal in magnitude and one end of each segment is kept at ground potential. In an energy supply and an accelerator according to the present invention, a switch controlling the application of the voltage over the primary winding has controlled turn-on and turn-off preferably is an IGBT switch.
