Project 1

1)Buck converter (CCM): It is Dc-Dc converter .It gives ouput voltage less than input voltage .

So it is also known as step down converter.

2)Boost Converter:It is used to step up the voltage.Here output volatge is graeter than inpiut volatge .

It is also known as step up DC-DC converter.

3)SEPIC Converter:The single ended primary inductor converter(SEPIC) is a type of DC-Dc converter allaowing electrical volatge  ata ist o/p to be graeter than ,less than ,or equal to that at its input .The o/p of SEPIC is controlled by duty cycle .

Schamatic:

Given data,Vin=30-60V, Vo=45V ,p=1000W
