Digital controller design for interleaved boost converter in photovoltaic system

In this paper is presented the design of a discrete control system with double loop for a photovoltaic system using interleaved two levels boost converter. For design of discrete compensators used in this work the delay time of the digital systems is considered in order to improve response of controllers. An easy method to design the compensators it is presented using the continuous time analysis and the addition of the delay time. Finally, the discrete compensator is validated through the simulation results performed by using the PSIM software.
