In the circuit below Vac is the power outlet voltage in North America: 120 Vrms @ 60 Hz. The forward bias diodes Ds1 and Ds1 are represented as a constant voltage drop VD=0.7 V, CF1=1860 μF, CF2=1770 μF, the LEDs are also represented using a constant voltage drop of VLED-2 V, Rg1 = Rg2=470 2, RL1=148, and RL2=134 $2. a. Calculate the average voltage at terminal VPos. b. Calculate the ripple voltage at terminal VPos. c. Calculate the average voltage at terminal VNeg. d. Calculate the ripple voltage at terminal VNeg. Tip: Use the Thévenin equivalent circuit after the capacitor to calculate the load current. Vac No connection! TX mmm. 10:1 mmö Ds2 Ds1 9F F CF1 >>LED1 Rg1 CF2 LED2 Rg2 ww ww RL1 VPos RL2 VNeg
