Problem 2: A photovoltaic module is used to supply constant 12 V that needed by a Tablet. Depending on insolation from the Sun, the photovoltaic module’s output voltage is changing between 18 V to 36 V (dc). Thus, a buck converter is used between the netbook and the photovoltaic module. 1) What is the duty ratio range of the dc/dc converter? 2) If the inductance of the buck converter inductor is 40 uH, what is the minimum switching frequency to...

Full wave rectifier is used to design a DC power supply. The DC power supply has an average output voltage of 12v on which the maximum ripple allowed is 1v (peak to peak). The rectifier feeds a load of 200ohm . The rectifier is supplied from 170v at 60 hz ac line through a transformer. Assume Vy= 0.7v . a) Find the transformer tarns ratio? b) Find the required value of the capacitor? c) Specify the PIV rating of the...

Design a DC power supply that will deliver 100mA of current to a load with a ripple of 5%. Use a full wave rectifier and a 17 Peak Voltage Source with F= 60 Hz. Load resistance = 1k So Basically you just need to find the capacitance of the filtering capacitor. Please tell me how. This is what I did, but I think I'm wrong. The Vripple I got is (.05)*17 = .85 V. Then according to my manual, C...

A) You are in a situation where you need to control a load that draws 1A from an approximately 12V supply. The control signal that you have available is a 0-1V signal capable of sourcing 100mA. Choose a type of transistor to implement this control and show a circuit diagram for how you might hook it up. B) For this problem, the load and its power supply are the same as in the previous problem, but the control comes from...
