Electrical Engineering

A photovoltaic module is used to supply constant 12 V thatneeded by a Tablet. Depending on insolation from the Sun, thephotovoltaic module’s output voltage is changing between 18 V to 36V (dc). Thus, a buck converter is used between the netbook and thephotovoltaic 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 limit the current ripplein the inductor to less than 1 A? 3) At constant 12 V, what is theminimum power consumption of the Tablet to keep the inductorcurrent always continuous?

4) For the operation condition stated in 3), draw (not simulateand plot) the waveforms of i) switching status, ii)voltage crossthe diode , and iii) inductor current; mark the values for eachwaveform
