Abstract: (Sponsored by PELS TC 4)
Current source inverters (CSIs) have significant advantages over voltage source inverters for motor drives, including the elimination of electrolytic capacitors, smoother output currents, and resilience against short-circuit faults. Nonetheless, there are also significant disadvantages – the cost, masses, and losses of the DC link inductor and the need for reverse-blocking switches. However, for wound field synchronous motors, the field winding of the wound field synchronous motor can serve as the DC link inductance. This eliminates the additional mass, cost, and losses associated with a separate DC link inductor.
This webinar will discuss CSIs, the design of a wound field synchronous motor with the field winding serving as DC link of a CSI motor drive, and how the constant-power speed region can be achieved with this motor drive. Both simulation results and experimental results from a technology demonstrator will be presented.
