In this paper the design and the operation of the drive system in a Fuel Cell Electric Vehicle (FCEV) is presented. The system consists of a Proton Exchange Membrane Fuel Cell (PEMFC) stack, an interleaved boost converter, battery pack connected via a bidirectional buck-boost converter and a brushless DC motor (BLDC) driven by a three phase inverter. A basic analysis of each component of the in...

Multilevel power converters provide more than two levels of voltage to achieve smoother and less distorted ac to-dc, dc-to-ac, and dc-to-dc power conversion. This paper presents a generalized multilevel inverter (converter) topology with self voltage balancing. The generalized multilevel inverter topology provides a true multilevel structure that can balance each DC voltage level automatically ...

Three-level Z-source inverters are recent single-stage topological solutions proposed for buck-boost energy conversion with all favorable advantages of three-level switching retained. Despite their effectiveness in achieving voltage buck-boost conversion, existing three-level Z-source inverters use two impedance networks and two isolated dc sources, which can significantly increase the overall ...

Active filters provide significant harmonic and reactive power compensation and are thereby widely accepted as devices for power quality enhancement.. Many research works have been done to improve the dynamic performance of active filters. Current research work focuses on implementing a Minimally Switched Shunt Active Power filter for power quality enhancement. Minimally switched grid interacti...

In recent year, common mode voltage (CMV) elimination methods are considered to improve the reliability of three-level quasi-switched boost T-type inverter (TL-qSBT2I). The space-vector modulation method (SVM) can control operation eliminate CMV. proposed applies medium vectors and zero vector synthesize reference CMV while output is unchanged compared SinPWM technique. order prevent active fro...

A dual two-level inverter fed open-end winding induction motor drive with a single DCpower supply is proposed. The proposed scheme produces voltage space vector locations identical to those of a conventional three-level inverter. In the conventional neutral-clamped three-level inverter, the series-connected DC link capacitors carry the load current, resulting in a fluctuating neutral point. Als...
