A Modified DPWM With Neutral Point Voltage Balance Capability for Three-Phase Vienna Rectifiers
IEEE transactions on power electronics, 2021Compared with continuous pulsewidth modulation (PWM), discontinuous PWM (DPWM) is a preferred solution in high-frequency Vienna-type rectifiers due to its inherent characteristics of less commutation number and higher efficiency.

This paper investigates two conflictive issues of common-mode (CM) voltage reduction and neutral point (NP) voltage balancing in a three-level neutral-point-clamped (NPC) converter. The amplitude of NP voltage variation under CM voltage mitigation scheme has been derived analytically.

Analysis of Neutral-Point Voltage Balancing in Three-Ports Active Neutral-Point-Clamped Converter
2019 IEEE 15th Brazilian Power Electronics Conference and 5th IEEE Southern Power Electronics Conference (COBEP/SPEC), 2019This paper investigates the neutral-point (NP) voltage balancing problem from the perspective of the space vector modulation for different operating conditions of the recently proposed Three-ports Active Neutral-Point-Clamped (ANPC-3P) topology, which can integrate one energy storage system per inverter leg.
