chopper is a type of converter which converts fixed DC to VARIABLE DC.generally dc supply can't be step up or step down because transformer is the only device which is used to step up or step down the voltage/current, but by using choppers we can able to step up and step down the DC voltage/currents

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
pls,send the previous year written test questions.
