Operator based voltage control experiments of thermoelectric generation system

Boost converters have nonlinear characteristics by semiconductor switching elements in a circuit. Generally, controllers are designed by a linearized model of the boost converter based on state space averaging method. This study proposes design scheme considering discontinuous conduction mode without linearization. In detail, firstly, modeling of boost converter in discontinuous conduction mode is derived. Secondly, control system designed based on operator theory is shown. Finally, the effectiveness of the proposed control system is verified by simulation and experimental results to the change of the load and the input voltage.
