Effective nonlinear magnetic simulation using radspice

Abstract

SPICE has been used extensively by integrated circuit designers, but its use by the power electronics industry has been limited because of its lack of a nonlinear magnetics model. This paper describes the synthesis of such a model and its installation in RADSPICE (1)· Methods for effective simulation techniques when using nonlinear magnetics are given. The model and methods are demonstrated through the accurate simulation of a closed-loop feedback magnetic power oscilltor.
