Ultrahigh Step-Up Switched-Capacitors-Coupled-Inductor Inverter

This article presents a new type of continuous input current magnetic coupling inverter. It employs a modified magnetic boost cell based on the new switched-capacitors-coupled-inductors technique. The proposed switched-capacitors-coupled-inductors inverter provides an ultrahigh voltage boost ability with a lower transformer's turn ratio. In other words, the high gain can be realized by lowering the windings number. As a result, the proposed inverter can bring forward a compact and low-cost system for high-voltage industrial applications. Likewise, regarding the semiconductors, short shoot-through duration and high modulation ratio can be used to achieve high output voltage, decreasing the switches’ stress and improving the output voltage and current qualities. The detailed analysis followed by experimental results is provided to prove the inverter's effectiveness.
