The main goal of this research is to design a new digital controller for a boost-switching converter in Continuous Conduction Mode (CCM), which operates in Voltage Mode Control (VMC). Boost converter transfer function in the mentioned modes have one Right Half Plane (RHP) zero and a pair of complex poles while their places are severely dependent on input voltage, reference voltage and converter elements. Parameters of the proposed controller have been obtained by using a meta-heuristic multi-objective optimization method to gain an improved converter behavior in startup, load change and reference voltage change conditions along with appropriate gain and phase margins. The proposed controller is a combination of a standard typeIII controller and a PID controller with complex zeros. Simulation and experimental results illustrate that converter performance based on the proposed controller has a significant improvement rather than typeIII controller. Main benefits of the proposed controller includes achieving a suitable response in whole range of converter operation, not to need a current feedback, appropriate stability and simple and cost-effective implementation.
