PLECS: Cuk Converter with Integrated Magnetics

This model highlights the PLECS magnetic domain components using a complex isolated Ćuk converter which is capable of zero-ripple operation. The magnetic circuit consists of two opposing E-cores spaced by air gaps, where two chokes and the transformer are combined into a single structure modeled as three separate permeances. These permeances are implemented using the Saturable Core component, and the flux magnitudes through each leg as well as a stray path can be monitored. During the simulation, the core material saturates leading to spikes in the output current.
