A high Step-up DC-DC Converter employs Cascading CockcroftWalton Voltage Multiplier by omitting Step-up Transformer
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 1
Abstract
In my paper possess a high voltage gain and devoid of using Step up transformer through a high step-up DC-DC converter based on Cockcroft-Walton (CW) voltage multiplier. Here the input was in low to DC voltage is boost up with the help of boost inductor in DC-DC converter. The n-number of stages CWvoltage multiplier is applying input as low to AC voltage to high output DC voltage. This afford gets a continuous input current with low ripple, high voltage gain, reduced switching losses, low voltage stress on the switches, diodes & capacitors and also improving efficiency of the converter. In my paper, strategic controlled steps retain two independent frequencies, one of which operates at high frequency to optimized size of the inductor while the other one operates at comparatively low in frequency according to the desired output voltage ripple. Finally this converter is authorized by simulation and experimental result is designed.
