Most of the AC-DC systems include an AC DC converter for power factor correction followed by an isolated DC-DC converter. AC-DC converters will introduce harmonics to the input current waveform as it contains nonlinear elements, so a suitable control technique is required to smoothen the input current to reduce harmonics. For high power applications,(More)
The process by which the world outside is seen is termed as visual process or physiology of vision. There are three phases in this visual process: phase of refraction of light, phase of conversion of light energy into electrical impulse and finally peripheral and central neurophysiology. With the advent of modern instruments step by step biochemical changes(More)
