N2 - A modified PWM switch model for DC-DC converters operating in continuous conduction mode (CCM) is proposed in this study. The modified model is based on the conventional PWM switch model. Compared to other modelling methods, the conventional model is versatile and easy to implement. However, it is typically restricted to a few topologies only. Therefore in this study, the proposed modified model expands the application fields, which includes the DC-DC converter with the coupled inductor; it can also be used in basic converters as a conventional topology. A high step-up buck-boost converter was built for this investigation to verify the accuracy of the modified model. The experimental results show that this modified model can accurately predict the characteristics of the system.
