What does the conditions mean? i have modelled in the matlab but don't know inductor value, capacitor value and duty cycle?

A boost PWM converter has the following data: VI = 125 to 350 V, VO = 380 V, PO = 6.8 to 68 W, and fs = 50 kHz. Compute the voltage and current stresses of the transistor and the diode. The parasitic resistances of the circuit elements are negligible. Implement the circuit in MATLAB/SIMULINK and verify the calculation with simulation results considering 4 working conditions that are (VImax , POmax), (VImax , POmin), (VImin , POmax), (VImin , POmin)

Ahmed Sabry Elbaz

To perform simulation, you need to calculate the values of Duty cycle, boost inductor, load resistance and output capacitor by using design formulas to make the converter operate in Continuous Conduction Mode according to specifications you mentioned.
