Abstract

Boost converters are widely employed in power electronics applications. The boost working in Critical Conduction Mode (CRM) guarantees significant improvement in the efficiency of the converter and is suitable to low cost applications. On the other hand, the One-Cycle Control (OCC) technique offers various advantages when compared to other control techniques for switching converters: overcomes nonlinearities; eliminates crossover distortion; does not use input current sensor and has stability in a large dynamic range while reaching zero error in just one switching cycle. This paper proposes an OCC strategy for the boost operating in CRM. Besides that, a tutorial design is presented. Simulation results for a certain designed case are provided to verify the theoretical predictions developed in the paper.
