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.

Paralleled inverters with zero common-mode voltage

2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016
This paper introduces a PWM method for paralleled inverters which can achieve zero common-mode voltage. The paralleled inverters are connected through coupling inductors to the load. Based on the voltage vectors in each inverter, paralleled voltage vectors are proposed to combine the reference voltage.
