Novel Level Shifted PWM Technique for Unequal and Equal Power Sharing in Quasi Z-Source Cascaded Multilevel Inverter for PV Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Conventional phase-shifted pulsewidth modulation (PS-PWM) is a usual switching technique for Z-source/quasi-Z-Source (qZS)-based cascaded multilevel inverters (CMIs) (qZS-CMIs). The PS-PWM scheme causes higher switching ...

The adoption of electric vehicles (EVs) have proven to be a crucial factor to decreasing the emission of greenhouse gases (GHG) into the atmosphere. However, there are various hurdles that impede people from purchasing ...
Comparative study of adaptive sliding mode and resonant controllers in fault tolerant five-phase permanent magnet synchronous motor drive
(
Springer London
, 2018 , Article)
This paper proposes a new fault tolerant control strategy for a five-phase permanent magnet synchronous motor (PMSM) drive under single-phase open circuit condition. The loss of one phase causes problems such as disturbing ...
