The post explains a how a simple IC 556 oscillator may be used to create a simple electronic ignition system. Standard automotive ignition coil has been used in conjunction with a dual timer 556 and MOSFETs employed to handle the power. This can be termed as an electronic ignition. In the dual timer section one half is being used for frequency generation and the other part switches the oscillator section with breaker points getting “closed” and “open”. . The frequency generator section in this circuit produces a rectangular waveform having frequency of 200 Hz. that drives the MOSFET. IRF 740 has a V-dss of 400 Volts and I-d of 10 Amperes sufficient margin in terms of Voltage and Current rating shall keep the switcher cool and efficient. Pin 8 and pin 12 are being driven by the breaker contact that in turn produces an inverted signal at pin 9. As pin 9 and 4 have shared logic state, this determines the state of pin 5 that drives the FET. The frequency determining elements are 15 K,...
