Active voltage balancing control with phase disposition PWM for 4-level flying capacitor converter

This contribution investigates three-phase four-level FLC based indirect frequency converter supplied from a 6kV AC-grid. It describes proposed active voltage balancing control of both output voltage-source inverter and input active rectifier with PD-PWM. The results are verified by experiments made...

Description
Summary:This contribution investigates three-phase four-level FLC based indirect frequency converter supplied from a 6kV AC-grid. It describes proposed active voltage balancing control of both output voltage-source inverter and input active rectifier with PD-PWM. The results are verified by experiments made on down-scale prototype of converter of rated power of 35kVA.
