Modeling of Average Current in Ideal and Non-Ideal Boost and Synchronous Boost Converters

This paper provides a modeling approach for average current control (ACC) operating in open-loop configuration. The converters chosen are non-ideal boost and synchronous continuous conduction mode (CCM). Initially, these mathematically modeled considering all the non-idealities using volt-sec amp-sec balance equations simulated MATLAB Simulink. transfer function of switch or inductor (Gid) to duty ratio is derived state space averaging (SSA) technique analyzed MATLAB/Simulink. It observed that Gid highly stable open loop. A larger magnitude resonance ideal than converters. However, low frequency gain crossover remained same. With increase load resistance, higher lower validated against standard model LTSpice software.
