Abstract: The waveform of lightning protection pin injection test for airborne equipment is a combination wave in which the open circuit voltage waveform is the same as short circuit current waveform. For such class of combination wave, a novel combination wave generator circuit was proposed based on the linear RLC circuit of impulse current. The relationship between the time of peak value, the peak current, the time of half peak value and damping coefficient parameter of the circuit was studied. A design method was proposed for combination wave circuit which the time of peak value and half peak value serve as target parameters. The circuit parameters of lightning protection pin injection test generator for airborne electronic equipment were obtained by calculation and simulation, taking account of the influence of the stray parameters. Simulation results show that the output waveform of the generator designed can meet RTCA/DO-160G standard requirements, and the generator could be used in lightning protection pin injection test for airborne equipment.

Key words: lightning, pin injection test, open circuit voltage, short circuit current, generator
