Theoretical analysis and experimental study on matrix transformer

Based on the lumped circuit model, parasitic elements of pulse transformer, turns ratio and impedance of load influence the rise time and overshoot of output waveforms is discussed. In this paper, the relationship of the parasitic elements between the standard pulse transformer and matrix transformer is analyzed in detail. Matrix transformer with the smaller leakage inductance and larger parasitic capacitances compares to standard pulse transformer. The standard pulse transformers and matrix transformer were designed and built. The experimental results showed that matrix transformer with the smaller δ compares to standard pulse transformer. the relationship of parasitic elements between pulse transformer and matrix transformer is the same to theoretic value.
