I have a doubt on how to select the inductor and capacitor value when I want to implement MPPT controller. This is because we always take a maximum output voltage and current but in this case, we only have the input values (Voltage open circuit, Current short circuit, Vmpp and Impp of the cell).
I have read some papers which take some advance techniques by taking the input impedance and making a relation between the output impedance and inductor and capacitor, but I want some more simply techniques since several thesis or papers that focused on the MPPT algorithm doesn't show how they designed the boost converter, instead they only put the values of those components
As I know in general, inductor and capacitor of the converter are designed based on the knowledge of some parameters like output voltage/current and input voltage/current, expected voltage ripple across load and switching frequency.
MPPT is coming into picture for maximum power extraction from solar panel . This is possible with control algorithms like PO sitting in digital control board which generates DPWM signals which in turn trigger the switching element in the converter.
Good luck for finding answer @Andres.G
Hi Andrés,
When I was dealing with that problem I took this paper as a reference:
Article Modeling of Step-up Grid-Connected Photovoltaic Systems for ...
That paper presents a complete procedure to design the passive elements of the boost converter. Notice that C and L are designed based on the voltage and currents ripples.
Later I developed further the methodology in this book chapter:
Chapter Analysis and Control of Power Electronic Converters Based on...
Some losses were considered as well as the converter inefficiencies.
I hope this material serves the purpose.
