I've been given these questions (attached) as part of my homework but im finding it difficult to answer them. Does anyone know how to? Would really appreciate your help!
Using either Voltage mode/Current mode PWM technique, we can make output voltage is stable. The rectifier input part will be a square wave with magnitude 120/370 depends on input. As the input fluctuates, the dutycle also chages accordingly. Then how can you predict the duty cycle. There should be some modifications in the questions they have asked, i hope.
Thanks Anand. A 50V output is required from the load on the right. If the input voltage to the bridge converter is 120V, how do I calculate the turns ratio?
