A buck DC to DC converter is applied with a voltage of 100 V and supplies a resistive load of 50 Ω. During ON state, it has a voltage drop of 2 V. The chopping frequency is 1 kHz and the duty ratio is 50%. Average and rms output voltages respectively are:
1
98 V and 69.4 V
2
24.5 V and 89.4 V
3
49 V and 89.2 V
4
49 V and 69.4 V
