Project 2

Aim

PV output voltage/ Input voltage of converter=250-350V

Output voltage= 600V

Rated PV power =100kW

Switching frequency=5kHz

Current ripple=5%

Voltage ripple=1%

Repeat the above using a two-stage Interleaved Boost converter and compare MATLAB results.

Ans:

MPPT circuitry will reduce the input current -> increase the input voltage until the combination current/voltage reaches the maximum power that the panel can deliver

MPPT charge controllers have the advantage of taking all the power the panel can put out and turning that higher voltage into the additional current. So if you take the same situation, the MPPT controller will use all 18V that the panel is putting out, and increases the charging current

The solar panels with built-in MPPT have fixed 5V or 12V output and work just fine without any battery.

MPPT solar charge controller is necessary for any solar power systems need to extract maximum power from the PV module; it forces the PV module to operate at voltage close to the maximum power point to draw maximum available power.
