Abstract

This project covered about the designing high voltage generator by using the ignition coil. The generator ignite voltage spark, up to lOkVand measured by special custom made probe before displayed the waveform on the oscilloscope. Although there are some experiments by using the ignition coil, the voltage determined is between 35 to 40KV, which is with a hyper close distance between the probe and the spark tip . First and foremost, verifying the output signal from the ignition coil. The confirmation need to be done as to make sure that the next experiment and work can be completely obey the output signal of the circuit. The designing process work smoothly in the time gap given since the signal is known. As this is a high voltage project, this part is important and compulsory. Then only the measurement part is applied. The measurement part is covered about the output voltage versus the distance. From the look-up table and the graph, the result is an exponential graph which means that the voltage parameters are inversing the distance. Since the driver used the 555 timer, the timer is tested due to two (2) different modes-astable and monostable. The timer output signal was displayed to make sure it will drive the igniters in the safe and correct mode. This project can be applied to act as a standard lightning surge model in the future if the original circuit is connected to certain specific route. It also will proceed as a tester in the electromagnetic compatibility and applied to the filtering part, where, by using Fourier series, we can develop a filter which can eliminate the unwanted frequency in the impulse signal.
