DESIGN OF SATURABLE REACTORS FOR APPLICATIONS IN POWER CONDITIONING SYSTEMS

This paper presents the design of saturable chokes for use in power electronics and power conditioning systems. The inductances computed based on the finite-element field solution are compared with the estimated nonlinear inductances from the actual measurements. The results have shown the adequacy of the developed three-dimensional finite-element (FE) simulation. The calculated field solutions are used to assist the quantitative study of the influence of the nonlinear choke air gap on the inductance characteristics for intended application in the choke design.
