Sir,
I have a small query reg Buck Boost converter,

1. If mode of operation is Buck , let i/p vol is 200 V , my doubt is what the minimum voltage we can get , and how this will be decided in practical ckts as well as simulation ckt

In similarly

2. If mode of operations is Boost , let Input vol 24 V , then what max output voltage can be obtained at o/p , what factors affect this range of o/p voltage

Thank you sir

Thank you for the realy reply

and Let me correct .........

What changes to be done in the circuit if i want +ve o/p voltage ...

I simulated ur ckt for boost operation of 24 V input to 200 V output by setting duty cycle 89.23% (calculated from Vo/p / Vin = D/(1-D)) ...........

I got the output of -157 V , where i were wrong ......Plz help me.

Thank You

Respected Sir,

I am grateful and thanking you much for uploading DC DC converter Mathematical and MATLAB Simulink model that are simulated in your hands for public accessing and specially for students.

From your model, I am one of the such kind where received much technical information for my Uninterruptible Power Supply project . In which , your model helps me a lot regarding design of DC DC chopper and battery charger circuit.

Thanking you Sir

Yours Sincerely
