Guest mshh Posted November 29, 2013 Report Share Posted November 29, 2013 I am doing maximum power tracking (MPPT)for a photovoltaic cell (max current 4.4 A ,max voltage 34 v) i did the attached circuit to control current consequently get MPPT but the circuit go mad when i turned the potentiometer the current go up and down and didn't stabilize .I used this power supplyhttp://www.amazon.com/Mastech-HY3005.../dp/B000E14F56 to simulate the pv panel and adjust it to source 7 volt and it did well . i could change the current from 0-2 A when i tried to increase it upper than 7 v it went crazy . the led indicator called C.C changed to C.V every thing current and voltage go upside down ,and that what was happening with the pv panel. i don't know why . may be i should increase the number of mosfets.but i used four resistors 3.3Ω 7 watt instead of those in picture Quote Link to comment Share on other sites More sharing options...
