Abstract
In this paper, a small-signal model for a synchronous Pulse-Width Modulated (PWM) Boost converter operating in Continuous Conduction Mode (CCM) embedding a Zero Voltage Switching (ZVS) network for the high side power MOSFET is proposed. The exposed analysis aims at extending the field of equivalent circuit models for DC/DC power converters, presenting a fully characterization of the dynamical alteration of the Boost converter traditional small-signal model when the ZVS network is introduced. The enhanced small-signal model results in a convenient tool exploitable since from the beginning of the compensation network design phase, as it permits to capture the main open-loop converter transfer function alteration, i.e., the control-to-output, line-to-output and output impedance transfer functions. The validity of the provided small-signal model is demonstrated through a set of SIMPLIS circuital simulations.File | Dimensione | Formato | |
