This paper deals with non-conventional energy based DC-DC converter. The energy from the sun is abundant in nature. So, solar energy is widely used. Three port converter which converts DC of one level to DC of another level. This work deals with system efficiency and reduction of ripple in the output voltage. This converter uses three port to interface: first source port, second storage port and a...
The converter with high voltage gain is used for photovoltaic application. This paper presents quadratic boost converter incorporated with coupled inductor, voltage doubler cell and clamped circuit. This converter is used for stepping up the voltage of photovoltaic system. The coupled inductor primary side is connected to the capacitor of clamped circuit which reduces the voltage stress of power switch...
A Bi-directional parallel DC-AC and AC-DC resonant High frequency AC link power conversion system with non-isolated topology is designed and simulated in this paper. The results of forward and reverse flow of power are discussed in this paper. Increase in switching frequency decreases the switching losses and results in the improvement of overall efficiency. Under constant frequency 50Hz the filter...
This paper presents LLC series-resonant half-bridge DC - DC converter. This circuit is characterized by zero voltage- switching (ZVS) that results in higher efficiency. Possibility to incorporate higher switching frequency and has some potency to reduce switching losses. Power factor improvement and high efficiency is achieved with a constant output voltage and DC output voltage is regulated by using...
This paper presents the simulation of Half Bridge Series Resonant Power Factor Correction (PFC) DC - DC converter with high frequency transformer isolation using Matlab Simulink. Resonant converters have no switching loss and are more suitable for high frequency operations. The switches in resonant converters turn on and off under zero current and/or zero voltage and there is no switching loss.This...
