Performance analysis and simulation design of a soft switching Cuk DC/DC converter with controllers

This paper proposes a design simulation of a soft-switching Cuk DC to DC Converter with a single switch. By eliminating extra switches, the proposed converter can be controlled with a controller. A single MOSFET is used as a power switch that turns on at zero-current switching (ZCS) and turns off at zero-voltage switching (ZVS) conditions. Analysis of Total Harmonic Distortion (THD) between the proposed converter and two switched converter clearly showed the novelty of the suggested converter with improved quality. The proposed converter can operate at high switching frequencies and with high output for an extensive load scale. The simulation of MATLAB/ Simulink with 100W/50Khz soft-switched Pulse-width modulation (PWM) Cuk converter produced 100 W from 100 V input voltage while reducing current stress and extra switch loss. A comparison of the proposed soft-switched Cuk and conventional Cuk converter is taken into account. PID and PI controllers are employed in this study to investigate the performance and stability of the proposed converter. Under any influence of different parasitic resistance Ron of switching power devices, load conditions, and variable input voltage, the proposed converter can provide robust output voltage with improved dynamic performance operated with linear controllers.
