Hello,
I am working on C2000 launchpad with TMS320F28027 controller on it.
Currently I am working on SEPIC converter a small 500W power supply. I have tested the scheme with open loop (fixed duty cycle) system. Using the Feq_up_down example. It was a great help.
Now moving ahead I need develop a close loop for voltage control. Referring to varios posts on the forum I came to know that primary understanding of PI control and close loop implementation is provided in DMC library and IQ math .
My switching frequency in 100 kHz. and Vout is 72V and Vin is 40V to 100V.
My doubt is can i use these libraries for lauchpad also. How to start coding for close loop control as later I also need to implement the current loop.
Please help.
