Suppression strategy of neutral-point potential fluctuation in VIENNA rectifier based on zero-sequence voltage component injection

The neutral-point potential fluctuation in the VIENNA rectifier is one of the key factors affecting the charging performance of DC charging systems. To address this issue, the charging and discharging behavior of the DC-link capacitors under different switching states is analyzed...

VIENNA rectifier improved carrier pulse width modulation strategy

Purpose Aiming at the current zero-crossing distortion in VIENNA rectifiers caused by the phase shift between the modulation voltage vector and the input current vector due to grid-side filters, this paper aims to propose a hybrid modulation strategy combining reactive current in...
