This paper present a reduced order model of interleaved boost converter integrating coupled inductor and switched capacitor by decoupling the leakage inductance leading to resonant exchange with the switched capacitors. State space averaging method is employed to derive the small signal ac model with ideal components. Furthermore, a dual loop control is adopted to regulate the output voltage of the converter. Extensive analysis and simulation demonstrate that the proposed model although simplified is sufficient for an adequate control system design ensuring fast transient response and good output voltage regulation.
