Characteristics analysis and comparison of buck boost circuit and Cuk circuit

The characteristic study on the buck-boost and Cuk chopper circuit has an important role for optimal design of the DC-DC converter. Therefore, based on the given parameter conditions, the two chopper circuit models are constructed using software simulation integrated environment - Simulink of MATLAB, and the circuit characteristics are discussed, such as the output voltage, the circuit current and so on, which can help better understand the characteristics of these two chopper circuits, and provide a reasonable basis for the application of the chopper circuit. The simulation results show that the Cuk circuit is a hybrid circuit, the output current & voltage ripples are very small, and the current is continuous, these characteristics are beneficial for the input, output filter.
