Unformatted text preview: of at least 92%, how low must the inductance resistor be? 3) A buck converter supplies 10 volts at 5A to a load resistor. The input to the converter is 25V. The inductance is the value at the borderline of continuous/discontinuous operation. Switching frequency is 10 kHz. C is very large. a) Determine the duty cycle of the switch. b) Determine the maximum and minimum value of capacitor current. c) Determine the average diode current and transistor current d) Assume that we have 0.8V voltage drop across the transistor when conducting. Assume the same input/output conditions as above. Determine the duty cycle of the converter and the efficiency of the circuit....
