I have done a buck circuit using Pspice but i have some problem with the Voltage,power and current Output.
By calculation i should get 60V and 4kW for the output
Vo = 60V
Vin = 339.4V
Duty cycle,
T =50us
F = 20k
D= 60/339.4
=0.178
DT = 60/(339.4 ) x 50us
= 8.9us
Output Current,
Iout = Pout/Vout
= = 4000/60
= 66.667A
Resistance,
R =Vout/Iout =60/66.667
= 0.8999 Ω
but in simulation i get:
Average Voutput = 49.4V
Average Power = 2.67kW
Average power:
Average Voltage:
Seem way off from the calculation..
Im try to figure what to do, so,i can get the nearest value with the calculation. I hope someone can help me with my problem.
