I am asked to find the duty cycle ratios, D1 and D2, and their ripple frequency in the following circuit:
Vo is controlled to provide an average output voltage of 200 V.
What i've tried doing is setting up this equation:
V0 = Va - Vb = D1 * Vd - D2 * Vd
Resulting in:
200 = D1 * 250 - D2 * 250
From the looks of it, I need another equation so I can find D1 and D2. Where do I go from here ?
Thank you.
