Investigations of multi-carrier pulse width modulation schemes for diode free neutral point clamped multilevel inverters
(
Korean Institute of Power Electronics
, 2019 , Article)
Multilevel Inverters (MLIs) are widely used in medium voltage applications due to their various advantages. In addition, there are numerous types of MLIs for such applications. However, the diode-less 3-level (3L) T-type ...
Selective harmonics elimination in multilevel inverter by a derivative-free iterative method under varying voltage condition
(
ISA - Instrumentation, Systems, and Automation Society
, 2019 , Article)
Selective Harmonics Elimination Pulse width modulation (SHE PWM) presents an alternative modulation technique to operate medium voltage medium and high power converters as it reduces the switching losses. SHE PWM generates ...
Selective harmonic elimination in awide modulation range using modified Newton-raphson and pattern generation methods for a multilevel inverter
(
MDPI AG
, 2018 , Article)
Considering the aim of having low switching losses, especially in medium-voltage and high-power converters, the pre-programmed pulse width modulation technique is very useful because the generated harmonic content can be ...
Adaptive direct torque control using Luenberger-sliding mode observer for online stator resistance estimation for five-phase induction motor drives
(
Springer Verlag
, 2018 , Article)
Direct torque control is considered as one of the variable structure control techniques which are characterized by fast response, simplicity and provide direct control of both electromagnetic torque and stator flux by ...
