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 ...
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 ...
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 ...
Improved single-phase inverter topology is used to avoid the common-mode leak
age current in the transformerless PV grid-connected system. The condition of elim
inating common-mode leakage current in both the unipolar ...
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. ...
This seminar report presents a controlled single switch stepdown ac/dc converter
without transformer which can be used in voltages between 90- 230 Vrms. Instead
of a transformer, this topology consists of a buck dc/dc ...
A single-phase series-resonant soft-switched ac chopper without auxiliary switches
with an efficient control circuit is presented. Basic working principle is series-resonant
conversion without any cycloconversion action. ...
This seminar report entitled ”Interleaved Active Clamped Dc-Dc Converter with

Nowadays developments are occurring in the field of sustainable energy sources.
Sustainable energy sources like photovoltaic systems and fuel systems require differ
ent levels of power supplies. Traditionally, transformer ...
The conventional two-stage power converters with bridge rectifiers are inefficient
and may not be practical for the low-voltage microgenerators. This report presents
an efficient ac-to-dc power converter that avoids the bridge ...
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 ...
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 ...
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, ...
A bidirectional dc-dc converter with high step-up and step-down voltage gain is
handling in this seminar paper. High voltage gains are obtained by employing a
coupled inductor with same primary and secondary winding turns ...
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 ...
