Design of DC pulse igniters

• High Voltage Pulse Generation Circuit:

  This circuit consists of components such as transistors, capacitors, resistors, and inductors, which together form a circuit capable of producing high voltage pulses. Transistors are used to switch on and off rapidly so as to control current flow through the circuit. Capacitors are charged up with low voltages before being discharged suddenly across ignition coils for generation of desired high voltage pulses. The rapid change in current flow through inductors produces strong voltage pulses in the coils. These components work together systematically to generate high voltage pulses needed for ignition.

• Pulse Transformer:

  Pulse transformers are used to step up voltages and isolate circuits electrically. They have primary and secondary windings that transfer energy from one to another as the current is changed rapidly. The fast changing magnetic field in the core due to current changes induces high voltages across secondary windings. These transformers allow igniters to generate high voltages while keeping circuits isolated for safety.

• Oscillator Circuit:

  Oscillators produce signals that repeat themselves in a regular pattern. Igniters use them to generate high frequency pulses needed for ignition. An oscillator circuit consists of components like capacitors, inductors and feedback loops that work together systematically to produce signals that oscillate. Capacitors and inductors form resonant circuits which amplify signals. Feedback loops allow outputs to be fed back into inputs so that signals keep building up. These components enable oscillators to generate useful repeating signals for ignitions.

• Microcontroller/Control Circuit:

  Microcontrollers are small computer chips that can be programmed to control various devices. In igniters, they manage timing sequences and pulse characteristics for ignition. Control circuits consist of logic gates, timers, and other digital components that work together systematically to make decisions and perform calculations. These circuits allow precise control over igniter functions. Using microcontrollers enables flexible and intelligent control of igniter operations. They can run different ignition sequences based on what is required at a particular time.
