Hello All,
i will be very grateful if anyone managed to help me with this.
i'm suppposed to design a boost DC-DC converter with the follwing specifications :
*Vo = 18v

i'm suppposed to design a boost DC-DC converter with the follwing specifications :
*Vo = 18v
1- The inductor current must be continuous under all operating conditions.
2- The peak-to-peak output voltage ripple must be less than 5%.
3- Design for a supply voltage that can change between 9V and 15V.
4- Design for a load current that can be in the range of 0.1A and 2A.
5- The regulator must keep its output regulated against load and supply disturbances i.e.
closed loop control is required.
i calculated suitable values for L & C and now i' have to use the IC TL494 to control the output of the converter in a voltage mode control .
f=10khz
can someone help me with the TL494 design ?
here is a schematic of what i reached so far
