DC-DC converter is a converter where we are regulating the input voltage to get the desired output voltage which is either greater than or equal to or less than the input voltage with positive or negative polarity. A lot of dc-dc converters are available in the world out of which SEPIC (Single-Ended Primary-Inductor Converter) converter is one of them. To analyse the converter, a lot of techniq...

This paper presents two current control techniques of an ac-dc boost converter to obtain unity power factor (PF). Single phase high power factor rectification is the most frequently accomplished using a boost converter. This converter reshapes distorted input current waveform to approximate a sinusoidal current that is in phase with the input voltage. There are several current control technique...

In this paper, a three-level integrated ac–dc converter with power factor correction is presented. The proposed converter integrates the operation of the boost power factor correction and the three-level dc–dc converter. The converter is made to operate with two independent controllers—an input controller that performs power factor correction and regulates the dc bus and an output controller th...

The self-oscillating flyback converter is a popular circuit for cost-sensitive applications due to its simplicity and low component count. This paper presents self-oscillating fly-back converter for mobile batteries charging applications. The converter is designed to step-down the high voltage input to an acceptable level from 220 VAC to 7VDC. By adding indictor and capacitor the power factor a...

The objective of this paper is to propose a three input boost converter for the hybrid system in order to simply the power system reduce the cost. The proposed converter having two source act as a input and third source act as a storage element. Supplying the output load, charging or discharging the battery can be made by the PV and the wind power sources individually or simultaneously. The pro...

Reduced switching loss favours Pulse Skipping Modulation mode of switching dc-to-dc converters at light loads. Under certain conditions the converter operates in discontinuous conduction mode (DCM). Inductor current starts from zero in each switching cycle as the switching frequency is constant and not adequately high. A DC-to-DC buck converter is modelled and simulated in this paper under DCM....
