संकल्पना:

अधिकतम शक्ति अंतरण प्रमेय(MPPT)

अधिकतम शक्ति के लिए शर्त:

RL = Rth

MPPT के दौरान भर में अधिकतम शक्ति:

Pमैक्स = \( {(V_{th})^2 \over 4 R_{th}}\)

जहां Vth = थेवेनिन वोल्टेज

Rth= भार टर्मिनल या थेवेनिन के प्रतिरोध से समतुल्य प्रतिरोध

गणना:

MPPT के दौरान:

RL = Rth

तो, संशोधित आरेख नीचे दिया गया है:

F2 Savita Engineering 20-4-22 D29

RL में वोल्टेज विभाजन नियम लागू करने पर:

\(V_L = V\times {R_L \over R_L+2}\)

\(V_L = 5\times {2\over 2+2}\)

VL = 2.5 वोल्ट

Shortcut Trick MPPT के दौरान भार के पार वोल्टेज हमेशा आपूर्ति वोल्टेज के आधे मान का होता है।

\(V_L= {V_S \over 2}\)

\(V_L= {5\over 2}\)

VL = 2.5 वोल्ट
