Maximum Power Transfer In Ac Circuits. If the load resistance is lower or higher than the theveninnorton resistance of the source network its. In a linear network having energy source and impedances maximum amount of power is transferred from source to load impedance if the load impedance is the complex conjugate of the total impedance of the network ie.
The maximum power transfer theorem is not so much a means of analysis as it is an aid to system design. Maximum power transfer theorem states that the dc voltage source will deliver maximum power to the variable load resistor only when the load resistance is equal to the source resistance. Draw the thevenins equivalent circuit hence the circuit is purely inductive.
Find the value of rl in figure 3 that results in maximum power transfer and find the maximum power delivered to load.
Based on this technique and with the maximum power transfer theorem for dc circuits we can determine the conditions for an ac load to absorb maximum power in an ac circuit. In a linear network having energy sources and impedances the maximum amount of power is transferred from source to load impedance if the load impedance is the complex conjugate of the total impedance of the network. Network the maximum power transfer theorem in ac circuit stated as follows. A lot of microwave design involves moving signal power most efficiently from one place to another.
