A new implementation of PI controller for quasi-resonant converters

https://doi.org/10.58571/CNCA.AMCA.2022.047

Resumen: The main contribution of this paper is to increase the operating range of quasi-resonant DC-DC converters through the implementation of a PI controller, considering the relationship between the duty cycle and switching frequency. Quasi-resonant converters use a soft switching method where the power devices switch at zero voltage or zero current, resulting in low switching loss and high power density. The controller design is carried out by applying the evaluation of the power stages in the topology with the aim to ensure soft switching commutation. Simulation results are presented to illustrate the features of the proposed estimation.
