Ultra-High Voltage Boost Converter using Multistage Topology

This paper presents an Ultra-High Voltage Boost Converter using Multistage Topology that achieves ultrahigh voltage gain with minimal power losses. The proposed converter integrates a dual-stage boost converter, a coupled inductor, and a voltage multiplier cell, enabling efficient energy transfer and recycling of leakage energy. The converter ensures continuous input current, reduces voltage stress on power switches, and decreases passive component size. With its high voltage gain, high efficiency, and compact design, this converter is suitable for various applications, including renewable energy systems, electric vehicles, and high-voltage DC transmission systems
