What is impedance matching

Explain the need for impedance matching

Impedance matching means equalizing the impedance of the source and that of the load. Impedance is the opposing of the electrical current by the circuit or by a section of the circuit for maximum power transfer the input impedance of a circuit must be equal to the output impedance of the other circuit. Impedance matching is very important in transformer parallel operation this impedance mismatch Will affect the real power output
