Abstract: Large engineered adjustable-speed-drive (ASD) systems are typically rated above 7 kV, with 5,000 or 10,000 hp considered engineered products and systems (i.e., one-of-a-kind or one-off designs) as opposed to off-the-shelf equipment. As such, they require… read more here.

DOI: 10.1109/tie.2022.3172758
Abstract: Electrolytic capacitors used in adjustable speed drives (ASDs) are affected more by low-frequency currents than high frequency. It is shown in this article that even-ordered harmonics in the supply voltage create a 150 Hz current… read more here.

DOI: 10.1109/tie.2022.3206695
Abstract: The current oscillations (ringings) associated with the voltage notches at the point of common coupling, caused by the function of diode rectifiers in adjustable speed drives (ASDs), can impair the power quality and make electromagnetic… read more here.
