Abstract :
A new type of sliding transformer with long magnetic core and movable secondary winding is presented. The basic transformer configurations and wiring are described. The magnetic flux distribution along the magnetic circuit and its influence on transformer parameters are discussed and examined. Also, the leakage inductance of the transformer primary winding, as the main cause of voltage drop and energy losses, has been discussed. The main experimental results of transformer model investigation are presented in this paper
