The Vienna rectifier power topology is used in high-power, three-phase power factor correction applications such as appliances, electric vehicle (EV) chargers, and telecom rectifiers. Control design of the rectifier can be complex. This design guide illustrates a method to control the power stage using the C2000TM microcontroller (MCU).
Three-phase power is used by equipment operating at high power in industrial applications. To improve grid power quality and reduce the harmonic currents drawn, power factor correction is needed as many of the forward loads are DC. For example, commercial air conditioner, EV charger.
Though many topologies exist for active three-phase power factor conversion, a Vienna rectifier is popular due to the operation in continuous conduction mode (CCM), inherent multilevel switching (three level), and reduced voltage stress on the power devices. Traditionally, hysteresis-based controllers have been used for Vienna rectifiers.
