File Information
Description

This package includes a configurable Simulink model for three different types of DC-DC converters (Buck, Boost and Buck-Boost converters) with a PWM PI controller. The example provided shows a case to boost voltage from 5 volts to 25 volts. It can be used to learn DC-DC converters and their control. The model itself also provides an example how to mask a subsystem in Simulink. A HTML and a pdf files are provided to explain the principles of the unform Simulink model for three different types of DC-DC converters. The model does not require other Simulink blocks, such as SimPowerSystems.

Required Products Simulink
MATLAB release MATLAB 7.5 (R2007b)

Default values for C and L are 440 and 20, respectively. I'm assuming the units are Farad and Henry. The default sampling frequency for the PWM is 0.2Hz. These are very odd values for a DC-DC converter. I changed components to 470microFarads and 22microHenries and changed PWM frequency to 25kHz. The results are not good.

This is a helpful model. If you are looking for more resources about pulse width modulation (PWM), please visit this web page.

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

at present i am working on this project "Digital Combination of Buck and Boost Converters
to Control a Positive Buck–Boost Converter and
Improve the Output Transients" can you help with the code or documentation i need simlink for pwm can please reply my mail id is pasumarthi.ram@gmail.com

Hi,Dr. Cao
Thanks for your excellent work!
I don't understand the PWMPID controler, Could you tell me why did you design the controler like that?
Thanks!

Hi,
I was wondering if there is any way to use this DC-DC converter with some of the electric drives in the SimPowerSystems library?

CyberWalker,

Thanks for suggestions. A pdf file has been added to the zip file to explain the model and general priniples of DC-DC converters. Please let me know if you find any error of the document.
