Abstract
Non-isolated DC-DC converters are fundamental building blocks in the power supply for a wide range of applications. To cater to this heterogeneity in applications, development of DC-DC converters with suitable voltage conversion ratio is imperative. This paper presents a simple procedure to obtain a converter topology from the required voltage conversion ratio. This method utilizes the principle of inductor flux balance as a synthesis tool. The proposed method is applied to synthesize various quadratic buck-boost topologies, and a family of converters was identified. Operation and feasibility of two novel topologies, identified by the proposed theory, are verified experimentally.
