Tool/software:
Hi team,
I hope you can help with a SEPIC converter issue.
My customer is trying to analyze an existing SEPIC converter design that has three simultaneous operating conditions: peak current mode control, coupled inductor, discontinuous conduction mode. They are trying to calculate the control loop parameters: gain, poles and zeros, stability. They can find no scholarly articles that address all three of their conditions together. Does TI have such a reference - can you please share?
They tried using SEPIC LM5155_56 Excel quickstart calculator (SNVR481). It seems hopeful, but there is a field in “Step 2: Filter Inductor” that allows switch from continuous conduction mode to discontinuous conduction mode that seems stuck in continuous mode. How can they change modes?
Regards,
Obinna.
