Abstract: All internal combustion engines are using spark ignition system; this system contain inductance converts low voltage to high voltage “thousand voltes”. At this state the principles of system are the primary coil of ignition system has a heavy wire with few turns. The secondary winding consists thousand turns of small wire. Its mean the energy that stored in the magnetic field of core will be same as the energy which transformed from spark plug. This design will give spark reaches spark plug at limited times to ignite the fuel engine. This system is working at high efficiency. The ignition coil steps up 12 V battery to high voltage required in combustion engine to make the current jumping from low to high current at spark terminal. By used technical power electronic 4 MOSFET as bridge making the EMF reach more than 25000 V in the modern ignition system high resistance is simulate and present in MATLAB (Simulink and code).
