Transformer-Less Boost Converter With Reduced Voltage Stress for High Voltage Step-Up Applications

In this article, a new transformer-less boost converter (TBC) is proposed to achieve high step-up voltage with a reduced voltage across switches. The proposed topology has the advantage of providing a high voltage gain, low voltage stress on the active switches, simplified control, and high efficiency. The structure is derived by modifying the classical switched inductor boost converter (SIBC) by ...
