(c) A testing had been done on buck converter as open loop system by varying the duty cycle from 0.5 to 0.9. The reading of voltage output is recorded as shown in Table Q3(c). We want to design a controller in the microcontroller. The microcontroller can tolerate the voltage from a sensor in the range of 0V to 3V.
