PWM Techniques for a 13-Level Asymmetrical Dual Inverter Configuration without the Overcharging of Floating Capacitor

© 2020 IEEE. This paper presents a PWM technique for an asymmetrical dual inverter with a floating capacitor bridge fed an open-end ac load. This technique is to prevent the inrush current during charging into the floating capacitor by using buck-mode operation and to regulate the dc-link voltage it...
