Microgrid power systems are becoming increasingly common in a large number of applications. In this paper,
the mitigation of the adverse effects of pulsed power loads on the microgrid systems is considered. In ...
Within the photovoltaic (PV) power-generation market, the ac PV module has shown obvious
growth. However, a high voltage gain converter is essential for the module’s grid connection through a
dc–dc boost converter. ...
The need for a voltage equalizer is principally due to the differences in cell chemistry, temperature gradients
along the battery string and the ages of the batteries. Therefore maintaining the charge level on each ...
Multilevel inverters have been widely accepted for high-power high-voltage applications. A reversing voltage nine level
inverter with Universal Control Scheme is presented in this paper. This topology ...
Current source drivers (CSDs) have been reduce the switching loss and gate drive loss in megahertz (MHz) dcdc converters, in which the duty cycle normally has a steady-state value. However, different from dc-dc converters, ...
Micro-dc grid is a novel power system focused on the development of renewable resources. However, two -wire
transmitting power mode is generally accepted in a micro -dc grid, which is usually not suitable for the ...
Nowadays developments are occurring in the field of sustainable energy sources.
Sustainable energy sources like photovoltaic systems and fuel systems require differ

This work proposes a fully directional dc/dc converter that interfaces the motor
drive of the vehicle with the energy storage system of the vehicle and the external
charger of the vehicle (only in case of PHEVs). This ...
This seminar report introduces new hybrid converter topologies which can supply
simultaneously AC as well as DC from a single DC source. The new Hybrid Con
verter is derived from the single switch controlled Boost and ...
This report focuses on best modelling of a photovoltaic cell by making it closed
loop. This model is based on mathematical equations and is described through an
equivalent circuit including a photocurrent source, a diode, ...
This Seminar report proposes a SVPWM controlled Z-source inverter in its buck
operation state, which is fed to the Induction motor which uses a PID controller for
its speed control. Z-source concept is gaining popularity ...
This seminar report presents a novel Interleaved Buck Converter(IBC) with feed
back control. Proposed IBC is suitable for application where input voltage is high and
operating duty cycle is less than 50% . In this IBC ...
Power factor is an important performance parameter of a system. If the power
factor of a system is low, it draws more current from the supply. So improving power
factor is very much essential for better and economic ...
