stability of pwm boost type dc-dc convertor

[jcpu]

hi,

need help to design /analyse open / closed loop
of pwm boost type dc-dc convertor.
best if we can have BODE plot
to fix those inductor, capacitor,... values

thanks in advance.

You can try with the book:
Switch-Mode Power Supply Spice Cookbook
Christophe P. Basso, McGraw-Hill

But you didn't mentioned if is boost voltage mode or current mode

please take a look at the many application notes found on the Texas Instruments web site. Look under the Training section and for the Unitrode power seminars.

fundamental of power electronics is also a good book to determine the small signal properties of power converters. The analysis in the book will be very helpful for designers.

The book has some dc-dc behavior Model example. You can use the model

to run the AC analysis with you compensation error amp.
