What is a bipolar PWM inverter?

The inverter terminal voltages are obtained denoted by VAN and VBN and the inverter output voltage VAB = VAN-VBN. Since the waveform of VAB switches between positive and negative dc voltages this scheme is called bipolar PWM. IV. UNIPOLAR PWM INVERTER

What is unipolar PWM method in three-level diode clamped inverter?

A. Unipolar PWM Technique applied to Three-level Diode Clamped Inverter. The unipolar PWM method offers a good opportunity forthe realization of the Three-phase inverter control. In caseof the three level inverters it is better to use theunipolar PWM method with three carrier waves. In such case the motor harmoniclosses will be considerably lower.
