In the analysis above, no dissipative elements (resistors) have been considered. That means that the power is transmitted without losses from the input voltage source to the load. However, parasitic resistances exist in all circuits, due to the resistivity of the materials they are made from. Therefore, a fraction of the power managed by the converter is dissipated by these parasitic resistances. WebMay 22, 2024 · The voltage across the resistor R2 is the output voltage and we found it to equal: v o u t = R 2 R 1 + R 2 v i n. Consequently, calculating the power for this resistor yields. P 2 = R 2 ( R 1 + R 2) 2 v i n 2. Consequently, this resistor dissipates power because P2 is positive. This result should not be surprising since we showed that the power ...
