Question 9 10 pts The transformer of a forward converter will operate at 50 kHz and the coil voltages are V1-V2-V3-90-V. The RMS current in each winding is 5.87-A. For a current density of 4.7 determ...
3.(25 pts) A forward converter is need to operate from DC source voltages that vary between 150 V and 350 Vand supply a load of 100 W at 5 V. The output filter has L = 10 pH and C=150 uF. The switching frequency is 40 kHz. Choose N /N3 =1. A. Select a transformer turns ratios N/N, to provide the required output voltage over the entire input voltage range. You can choose the range that D varies over (note...
