Analysis of a three-phase flying converter cell rectifier operating in light/no-load condition

A Hybrid Control Method to Suppress the Three-Time Fundamental Frequency Neutral-Point Voltage Fluctuation in a VIENNA Rectifier

“…This increased THD of input currents can be reduced using an enhanced control scheme as shown in [24]. Meanwhile, the VIENNA rectifier features an increased output voltage characteristic easily causing an overvoltage protection under the light load and especial for a no-load operating condition as mentioned in [28]. A specific circuit or control strategy should be used to make the system will work normally and remove the increased THD of input currents in these operating conditions, these are the author's future work.…”
