The switching of medium voltage electrical motors is typically realized by means of vacuum circuit breakers (VCBs) essentially in view of their elevated number of switching cycles. As known, switching of VCBs generates important transient recovery voltages ...
Electronic door lock cylinders need some sort of mechanical actuator to toggle the locking state between open and closed. The main requirements are high security standards, low power consumption, reasonable production costs, and facile integration of the a ...
Since control of a three-phase machine requires only two currents, it is possible to independently control a number of three-phase machines using reduced-switch-count voltage source inverter (VSI) topologies. One such configuration consists of n three-phas ...
Multiphase series-connected motor drives can be supplied from a two-level voltage source inverter (VSI), which has either a prime or a composite number of legs (phases). It has been shown recently that, in the case of a prime number of inverter/machine pha ...
This paper presents a study on the power conditioning features of hybrid powertrain, especially regarding diesel-electric locomotives. Equipped with an embarked energy buffer for diesel generator support and utility grid interface, such a locomotive can be ...
This paper presents a linear direct-quadrature (dq) current control strategy for voltage source converters (VSCs) in a rotating reference frame (RRF). The described method is based on Multivariable proportional-integral (PI) regulators and provides fast dy ...

Multiphase variable-speed drives supplied from two-level voltage source inverters (VSIs) are, at present, contenders for numerous industrial applications. Various pulse width modulation (PWM) methods for multiphase VSIs, aimed at sinusoidal output voltage ...
Several issues remain to be addressed for the commercial development of ResistiveFault Current Limiters based on superconducting technologies (RFCL). In particular, the inhomogeneity of high temperature superconducting coated conductors (HTS-CC) combined w ...
Multiphase variable-speed drives, supplied from two level voltage-source inverters (VSIs), are currently considered for a number of industrial applications. Although various multiphase pulsewidth-modulated (PWM) schemes had been recently developed, very li ...
A number of PWM techniques have been developed in recent times for five-phase voltage source inverters (VSIs), which enable sinusoidal output voltage generation. Relatively little attention has been however paid to the current ripple caused by these PWM me ...
