hi,

i want to control the output voltage and current of a Full Bridge power Supply built around UCC28950 using micro-controller . Is there any relevant design available?

regards
 

Hi,

Voltage:
* Either manipulate voltage_amplifier_reference_voltage (Formula 121, 122, 123)
* or manipulate the feedback path (124, 125, 126)
with a DAC.

yes, thats it, you need an external error amplfier, and you adjust the reference to it...perahops an error amp for current and one for voltage
