Project 1
AIM:
Design a DC-DC SEPIC converter with input voltage = 10 V, output voltage = 0-20VTake f = 50 kHz, ΔI1=ΔI2 =0.2 A, , Δv1=Δv2 =0.2V.Find the state space model of the converter
- Construct the converter in MATLAB and simulate
- Obtain the waveforms for input and output voltage, inductor current and capacitor voltage
- Repeat the above for Cuk converter
- Compare the results
