| Abstract | This paper presents the modeling of a boost converter operating in pseudo continuous current mode using hybrid automaton and proposes the voltage regulation problem as a hybrid control problem. The pseudo continuous current mode (PCCM) operation is treated as an intermediate stage between the continuous current mode (CCM) and discontinuous current mode (DCM) operation of a boost converter. From hybrid perspective, the control problem, the regulation of the output voltage, is framed as a guard selection problem and the guards are defined based on a simple circuit theoretical approach. A typical DC-DC boost converter is selected and the operation of the converter under the proposed control is demonstrated. It is observed that the control thus derived provides a good voltage regulation by operating the converter in a stable limit cycle for a given operating condition. The resulting switching operation has a variable frequency for different operating conditions. The simulation method, analysis and control design are explained and the results are presented. |
