Space vector pulse width modulation (SVPWM) is a superior switching technique offering several benefits for power electronic inverters. However, concerning multilevel inverters (MLIs), implementing SVPWM is a demanding and time-consuming task because it deals with the six sectors of the space vector modulation (SVM) plane and numerous regions and v...
The paper introduces a straightforward procedure for estimating the electrical parameters of a simple, but reasonably accurate, two-branches model of a supercapacitor (SC). The equivalent electrical circuit model includes the voltage and frequency dependence on the SC’s capacitance, neglecting the self-discharge phenomenon, so it is mainly devoted...
The evolution of power generation brings about extensive changes in other parts of the grid, especially in the transmission and distribution components. Within the scope of the Internet of Energy (IoE), electric power flows more flexibly between different parts of the grid. DC power will play an essential role in IoE. Decentralized photovoltaic pan...
Different maximum power point tracking (MPPT) techniques used in photovoltaic (PV) systems are evaluated based on several criteria such as simplicity, speed, and accuracy. There are tradeoffs among these criteria, and generally higher accuracy is achieved at the expense of speed and simplicity. The aim of this paper is to introduce Spline-MPPT tech...
Battery Pack life time depending on thermal management is a crucial issue in Electric and Electric Hybrid vehicles. Excessive thermal losses caused by the battery current ripples can be well avoided by introducing suitable topology. This paper proposes utilization of interleaved DC-DC converters to reduce the battery pack current ripples. Interleav...
In practice components used in energy conversion systems are not ideal. These non-idealities not only limit output voltage but also decrease efficiency of conversion. Non-ideality of inductors has considerable effect in comparison with other non-idealities in high current DC-DC converters. This paper proposes the interleave technique to reduce the...
