hi everyone,
Please help me with my third year BEng project "Designing SEPIC converter whose output is 5V to 20V and 1A current and also use micro controller as PWM controller (regulator)".
Problems
a. mosfet is not turning off.(both in simulation and practical)
b. snubber circuit which one is the best for sepic converter (i used rate of rise of voltage)
c. calculation to find the value of inductor(i.e. I calculated the L1 first and then made L1=L2. what happens if we calculate L2 first and make L2=L1?)
d. ground plane?
e. Does MOSFET driver necessary for 94kHz frequency ?
i have done simulation and calculation. I would like to know whether my calculation and simulation are right. I have attached my calculation and simulation result please help me I am stuck. Please give me some ideas. thank you
