Design and Analysis of Two Switch Boost Converter

Electrical And Electronics Engineering

High-gain DC-DC converters are becoming important in renewable energy systems, especially in solar power setups. This project introduces a new type of boost converter that does not use transformers or coupled inductors but still delivers a high-voltage output from a low-voltage input. It is designed to work well with energy sources such as solar panels or fuel cells, where the input voltage is usually low. Its simple design uses two switches, which are controlled by a single Pulse-width modulation (PWM) signal. This makes the entire system smaller, less expensive, lighter, and easier to manage. Compared with other similar converters, this method performs better in almost every area. For example, it can boost the input voltage up to approximately 15 times at a 60% duty cycle, and nearly 21 times at a 70% duty cycle. The efficiency is also impressive, ranging from 92% to 95%, which means that very little energy is wasted. Overall, this converter offers a reliable, efficient, and practical solution for renewable energy systems that require a high-voltage output from a low- voltage source.
