| Abstract | An IGBT three-phase unidirectional AC to DC power converter is presented which has reduced on-state and switching losses and sinusoidal input current. Use of linearised overmodulation, up to full rectification conditions, improves output voltage transient performance. Output filter capacitor current monitoring provides differential output voltage information for a PI and velocity controller. Output inductor current feedback eliminates triplen AC line components resulting from the use of an output inductor of finite inductance |
