A 10-Ohm fully resistive load system will be fed from a photovoltaic (PV) module. Load (converter output) voltage 12 V DC is required. But the PV output is DC 18 Volt. Buck type DC/DC converter design is required between load and PV. For this j-converter, the inductor current must be continuous and the fluctuation rate of the load voltage must be at most 0.5%. The lowest switching frequency is 40 kHz; A) What is the lowest Capacitor value (microF) that meets the design conditions for the output capacitor ? B) What is the RMS value of the inductor current (A) ? C) What is the average value of the inductor current (A) ?
