Design and Implementation of Closed-Loop Series Resonant Boost Converter

In this article, the proposed DC-DC boost converter offers a novel way to increase voltage gain while simplifying control methods. Unlike traditional boost converters, which usually require several components to manage basic functions, this novel design concentrates on accomplishing all control functions with a single low side switch. By simplifying the control system, this consolidation may reduce complexity and increase efficiency. A significant divergence from conventional boost converter design is the reorganization of the circuit architecture, specifically with the diode's location. In traditional configurations, the diode is typically placed at the boost converter's output. The suggested design, however, contradicts this arrangement by permitting both the natural input current from the source and the output capacitor's current to return via a series resonant network.

I. Introduction

DC-DC converters have grown in significance as a result of the quick development of technology. They are now essential components of many different applications, including solar photovoltaic systems, electric cars, mobile phones, industrial automation, battery chargers, and satellite power systems. These converters are critical components that greatly improve the usefulness and efficiency of contemporary electronic systems. The boost (step-up) converter stands out among the other kinds in situations where the output voltage must be greater than the input voltage, such in solar systems and LED drivers [1].
