As mentioned above, a 3 phase DC/AC inverter used in traction is supplied by a power net that can be either DC or mono-phase AC. In the case of AC supply, the (mono-phase) net is connected to the three-phase DC/AC inverter through a transformer and an AC/DC rectifier The connection line between the rectifier and the inverter is called DC link.

Brushless DC Motor Control Algorithms and Applications. Abstract. Brushless DC motors are high efficiency motors which are used across a wide variety of applications. These motors require more robust control algorithms then their brushed DC counterpart. BLDC motors are synchronous motors that require a 3-phase AC signal to drive them.
