DC TO DC CONVERTER WITH CONTROLLED ACTIVE CLAMPING SYSTEM
Introduction
Dc To Dc Converter is necessary to couple the solar cells operating at low DC Voltage to the inverters Dc links
Solar converters should have high efficiency
Solar converters can handle different voltages without loss
Need of The Study
Present converters have large size
They have reduced switching frequency
Low efficiency
Paralleling of several converter stages is necessary due to its current source characteristics
