A typical application using a three-phase, six-pulse rectifier is an
adjustable speed drive (Figure 5.7). Three-phase power (labeled phases
a, b, and c) is full-wave rectified by the six-pulse rectifier. The rectified
voltage is filtered by the high-voltage bus capacitor, Cbus, generating a
DC voltage, which is used by the subsequent inverter. The three-phase
inverter generates the three-phase currents necessary to drive the motor.
