A Common-Mode Voltage Elimination Method With Active Neutral Point Voltage Balancing Control for Three-Level T-Type Inverter

IEEE transactions on industry applications, 2022
Nowadays, the three-level T-type inverters (3LT2Is) are widely employed in applications with high-performance requirements. The 3LT2Is commonly suffer from neutral point voltage (NPV) unbalance and common-mode voltage (CMV) variation.

A Virtual Space Vector PWM With Active Neutral Point Voltage Control and Common Mode Voltage Suppression for Three-Level NPC Converters

IEEE transactions on industrial electronics (1982. Print), 2021
Virtual space vector pulsewidth modulation (VSVPWM) provides a new approach to neutral point voltage (NPV) control and common mode voltage (CMV) suppression. Few values of coefficients configured in the virtual vectors cannot adjust the NPV continuously.

Study of Common-Mode Voltage Measurements for IEC62684

IEEE Transactions on Industry Applications, 2013
This paper presents the study of common-mode (CM) voltage measurements for IEC62684 regulatory. Due to the digitization error caused by the limited vertical bit number of the analog-to-digital converter (ADC) in oscilloscopes, the CM voltage spectrum measurement of the flyback converter with AC source occurs significant inaccuracy.
