Multilevel inverters can reach the increasing demand for power quality and power ratings along with lower harmonic distortion and lesser electromagnetic interference (EMI). As the number of levels increases, it is important to control more switches in parallel with their…

Filaments operating at a high temperature region would require ripple free current constant power source for their heating purposes. Introduction of ripple in the power supply would result in high power loss, aberrant, unpredictable temperature rise etc. High current ripple…

Novel AZSPWM algorithms based on the concept of imaginary switching times (IST) are presented in this paper for vector controlled induction motor drive to reduce the common mode voltage (CMV) variations. The proposed algorithms did not use the information of…

Within the photovoltaic (PV) power-generation market, the  PV module has shown obvious growth. However, a high voltage gain converter is essential for the module’s grid connection through a dc–ac inverter. This paper proposes a converter that employs a floating active…

Since induction motors are preferred over direct current machines in the view of cost and simplicity, they have widely been used in industry. In this paper, the speed of the three-phase induction motor has been controlled using an indirect z-source…

This paper presents the implementation of Vehicle to Grid (V2G) technology for designing a shunt active filter to improve power quality of solar generation. A system model with solar generation and a dynamic model of PHEVs are introduced here based…

This paper proposed the power electronics solution to obtain variable speed of the variable-speed pump storage The study focused on the types of variable-speed pump storage consists of doubly fed asynchronous machine and power electronics converter. Power Electronics converters used…

The wind turbines based Doubly Fed Induction Machine (DFIM) not able to support the voltage and the frequency of the grid during and immediately following the grid failure. This would cause major problems for the systems stability, but the turbines…

This work presents the comparative study of the different PWM techniques to reduce the common-mode voltage (CMV) at the output of neutral point diode clamped inverter for variable speed drives. Here the comparative study is done by the phase opposition…

In this paper a new method of controller design for boost type dc-dc converter is proposed. A feedback controller for DC-DC boost converter is designed to obtain constant output voltage of 24v.The optimal values of feedback controller is obtained using…
