A chopper circuit is charging a 100 Ah battery from a \( 100 \mathrm{~V} \) constant DC supply. An ideal inductor of \( 60 \mathrm{mH} \) is connected in series to the battery. Assume that the battery voltage is constant during the operation and has zero internal resistance. I. Find the chopping frequency of the circuit to limit the charging current to \( \mathrm{C} / 10 \) when the duty cycle is kept at \( 20 \% \). II. If another battery of \( 65 \mathrm{Ah} \) (same voltage) is required to be charged at the same \( (\mathrm{C} / 10) \) rate from this converter, determine the duty cycle, pulse on-time and the frequency of operation.
