Abstract
This paper introduces a multiport phase-shifted switched capacitor converter that can be used in a DC-DC converter system that draws power from both solar panels and batteries. The proposed circuit uses a switched capacitor converter with multiple outputs and a variety of filters. The ZVS is the intended result of the design, and voltage stress reduction was a primary focus. The goal of minimizing the leakage current during soft switching. The 20 kHz frequency range was used for the simulation of a converter design. In order to lower the ripple voltage at the output, a cascaded-filter connection is made on that side. The converter has a high step-up voltage gain and reduces voltage stress on the power switch by striking the right balance between duty ratio and output voltage. By implementing a PID controller and a sliding mode controller, we can better control the voltage (SMC). Both open-loop and closed-loop simulation results are presented, and it is shown that they agree very well with the underlying fundamental analysis.
