Design of pulse-transmission transformer in inductive-coupling link

Propagation of the current pulse of quasi-rectangular shape through transformer in inductive-coupling link is investigated. This shape allows one to use MATLAB for simulation of transients in the transformer. One finds Z-parameters of the transformer circuit, and uses the step response of specially designed pulse-shaping network for simulation of the voltages at the transformer input and output. Comparing the output voltage with the derivative of quasi-rectangular pulse one finds the optimal inductances of the transformer. The level of parasitic capacitances when the link performance deteriorates is also found. The example of design is given for the pulse with duration of one nanosecond.
