A Simulation Study of Active Snubber Cell for A PWM DC-DC Boost Converter

Farah Samreen, K Shanmukha Sundar

This paper introduces a study of a new boost converter with an active snubber cell which is developed to overcome most of the drawbacks of conventional zero-voltage transition (ZVT) and zero-current transition (ZCT) converters. In the proposed work, the EMI noise is reduced by increasing the power density and efficiency of the pulse width modulation. In this converter, the snubber cell and all semiconductor devices will operate at soft switching even at higher switching frequencies. Further, additional current and voltage stress across the main and auxiliary components is limited. Simplicity in structure, ease of control and soft switching are the main advantages of the circuit. The results of the proposed topology are studied in detail through simulation and results are presented with a high efficiency of 98%. The proposed work demonstrates the feasibility of the converter through simulation results.
