ABSTRACT:
Ignition apparatus for providing plasma ignition for an engine, which ignition apparatus comprises a switching circuit, a wave form generator for generating an a.c. wave form output, a power amplifier circuit for amplifying the output from the wave form generator, a d.c. to d.c. inverter, and a transformer having primary and secondary windings, the primary winding being connected to the power amplifier circuit for receiving the output from the power amplifier circuit, and the secondary winding being connected to the d.c. to d.c. inverter, and the wave form generator and the d.c. to d.c. inverter being connected in parallel so that during operation of the ignition apparatus high voltage a.c. from the wave form generator carries and sustains d.c. which is from the d.c. to d.c. inverter and which is required for the plasma.
