Deep-going Study on Reflected Impedance for Air-core Transformer Circuits
The existing textbooks using reflected impedances to analyze air-core transformer circuits,seldom clarify reflected and loop impedances in detail and only take simplified circuit networks as the analysis samples,which make readers still confuse about the circuit calculation of complex transformer networks.Both reflected and loop impedances are clearly discussed in this paper,and a decoupling equivalence model and a series of universal extension formulas of reflected impedance are clarified,with two complicated circuit examples.Under the clear clarification of loop impedances and open circuit voltages,by utilizing the proposed formulas of reflected impedance and open circuit voltage,both primary and secondary currents of any complex air-core transformer circuits are directly calculated,which enriches the teaching of reflected impedance for air-core transformers.
