摘要

In a conventional step up converter, the potential across the load is always positive and greater than the source voltage. However, certain applications require a negative output voltage. The Re-lift Negative Boost Converter addresses this need by both inverting the output polarity and increasing the voltage level. This accomplished using a specific arrangement of inductors, capacitors, and switching devices. This paper details the design, simulation and analysis of a Re-lift Negative Boost Converter utilizing Zero voltage switching (ZVS) to improve efficiency and reduce electromagnetic interference (EMI) in open loop and closed loop. The converter engineered for high voltage gain with a negative output, making it ideal for renewable energy systems and electric vehicle applications. The integration of the ZVS technique reduces switching losses, enabling the converter to function at maximum frequencies with enhanced performance.
