3‐D CALCULATION OF MAGNETIC FIELD AND INDUCTANCE OF A REACTOR, WITH OPEN MAGNETIC CORE, BY INTEGRAL EQUATIONS METHOD

The reactor with rectangular shape of the winding turns and open magnetic core has been considered in the work. The integral equation has been solved numerically and components of magnetic flux density as well as leakage inductance of the winding have been computed for the object. A computer program for the analysis of magnetically open problems and a procedure, for numerical calculation of inductance, have been worked out. The computer codes were implemented for IBM PC/AT. The calculations were verified by measurements for physical model of the reactor.
