Query: A Comparative study of Analog and digital Controller On DC/DC Buck-Boost
  Converter Four Switch for Mobile Device Applications   This paper presents comparative performance between Analog and digital
controller on DC/DC buck-boost converter four switch. The design of power
electronic converter circuit with the use of closed loop scheme needs modeling
and then simulating the converter using the modeled equations. This can easily
be done with the help of state equations and MATLAB/SIMULINK as a tool for
simulation of those state equations. DC/DC Buckboost converter in this study is
operated in buck (step-down) and boost (step-up) modes.
