Hi , I am doing a project on MPPT controller. I am using PIC micro controller to generate the PWM signal. Solar panel VOC 23V, Isc=8.5A, Vmp=17.5V and Imp=8A.
Trouble is dc-dc converter. I have tried making a buck boost and cuk. As soon as I switch on the power supply (which is being used in lab instead of solar panel) the supply becomes a current source and starts giving 5A (maximum it can). Output voltage remains almost zero. any idea where the problem may be? or any design ideas for dc/dc converter.
