Boost Peak Current Mode Control – PCMC Open to Close Loop

Sarah Lynch_20319

A boost converter with peak current mode control (PCMC) with a close voltage loop will be designed from open-loop to close-loop with PSIM & SmartCtrl. The open-loop transfer function will be simulated without needing to convert to average models. The sub-harmonic oscillations associated with duty cycles greater than 0.5 will be observed and slope compensation will be calculated and introduced to maintain stability at higher duty cycles.
