Design of Double Closed-Loop Boost Converter Controller to Reduce Transient Voltage Dip for Sudden Load Connection

The paper presents a double closed-loop boost converter controller. For regulating output voltage of the boost converter a capacitor, a power switch, and a diode are used. The traditional buck-boost converter has a simple design that achieves high efficiency. Simulink is used to simulate a double closed-loop controller in this manuscript. A double loop is made up of an inner and an outer loop. The outer loop supplies the controller with boost output voltage, while the inner loop supplies the controller with inductor current. The sliding mode controller is regulated by inner loop, whereas the PI controller is regulated by its outer loop. The suggested system is capable of high-voltage photovoltaic applications by using inductors and low-voltage semiconductor devices. The dual closed-loop controller contributes to the achievement of a stable DC output voltage. The converter is capable of producing a broad range of noninverting output voltages. The proposed converter surpasses traditional models in terms of efficiency, voltage gain, ripple content, and dynamic responsiveness. This closed-loop system is durable and dependable, with constant transients and output voltage.
