Abstract:
1. A high frequency pulse generator having a sequential pulse voltage ignition system coupled to a light source comprising: an igniter to ignite the light source at substantially the lowest voltage based on the operational characteristics of the light source; DC injection circuitry operably coupled to the igniter, the DC injection circuitry including a DC source, a diode and inductance, the DC injection circuitry having operational parameters that is configured to be changed to modify the DC waveforms delivered to the igniter and powering the light source based on the operational characteristics of the light source; AC circuit operably coupled to the light source and operably coupled to an AC source, the AC circuit including igniter bypass switches having an open configuration and a closed configuration so that when the igniter bypass switches are closed AC is provided directly to the light source to bypass the igniter and the light source is supplied with AC only; and control circuitry operably connected to the DC injection circuitry and to the AC circuit to control operation of the DC injection circuitry and the AC circuit so that alternatively DC alone, DC with superimposed AC, or AC alone is provided to the light source based on the operational characteristics of the light source.
