Project 1 - Loss calculation for a DC/DC converter-MATLAB

i take this value

Vin = 100 V   , Vout = 200 V, P= 4000 watts, fs = 200kHZ

Efficiency calculation

Input voltage = 100V;

Input power = 4000watts

Input current = P/Vin = 4000/100 =40 A

In our theoretical calculation output power

Output voltage =200V;

Output current = 20A;

Output power = VI = 200 *20 =4000 watts

Input power and output power equal in theoretical

But in the original case we get current ripple and switching loses and diode forward voltage loses also there then our put not come 100% efficiency but we are design closed to the 100

First we are get results in this circuit

In our simulation output power

Output voltage =195 V;

Output current = 19.5 A;

Output power = VI = 195 *19.5 =3803 watts

In our original efficiency is 95.1%

In total loses is 4.9%
