The Y-source converter is one of the recent proposed impedance source converters. It has some advantages as having a high voltage gain between the input and output voltage sides using very small duty cycle ratios. For many applications, the input voltage needs to be boosted to higher output voltage, such as for fuel cell, battery electric vehicles and renewable energy applications. Understanding the...
In battery supplied multilevel converters it is a common problem to maintain the energy balance between the energy storage placed in different modules. Large unbalance between the state-of-charge (SoC) appears when a damaged battery module is exchanged, and with high probability the newly inserted battery module has different SoC than the other modules. In case the unbalance is large it takes long...
For most of the Multilevel Converter (MC) applications a commonly discussed issue is the maintenance of balance between the energy storage elements from the SubModules (SM). In applications where a battery pack is also part of the SM storage, such as STATCOMs or motor drives, the SM voltage is not in linear relation with the State Of Charge (SOC) of the entire battery; thus, the balancing becomes...
Boost converters are needed in many applications that require the output voltage to be higher than the input voltage. Recently, boost type converters have been attracted by the industrial applications, and hence it has become an extremely hot topic of research. Recently, many researchers proposed the impedance source converters with their unique advantages as having a high voltage gain in a small...
The use of electric vehicles (EVs) is advantageous because of zero emission, but their market penetration is limited by one disadvantage, i.e., energy storage. Battery EVs (BEVs) have a limited range, and their batteries take a long time to charge, compared with the time it takes to refuel the tank of a vehicle with an internal combustion engine (ICE). Fuel cells (FCs) can be added to an EV as an...
