Mathematical description of a power supply source for contactless energy supply as a control system element
The task of compiling a mathematical description of a two-winding single-phase transformer with an air gap used in a vehicle with a contactless power supply from a cable laid in the road is solved in the work. The power source is located under the carriageway of a road, and the receiver is on the board of a vehicle. Contactless energy transfer is carried out according to the principle of an air-gap transformer. A block schematic diagram of an air-gap transformer as an automatic control system element is developed in this work. In contrast to the well-known mathematical description, the article takes into account that a magnetic core material, a core area in an air gap and an air gap size are changeable. The resulting block schematic diagram allows analyzing and synthesizing the automatic control system of a vehicle taking into account properties of a contactless power source. It also helps to optimize processes in the projected system.
