Beschreibung
Zusammenfassung:	The invention is directed to a dual charge rate power supply circuit and method for ionization detection. The circuit includes a first diode D1, first and second capacitors C1, C2 and first and second current paths. The first diode includes an anode operably connected to a first end of a primary winding 16. The first capacitor C1 has a second end operably connected to ground and the second capacitor C2 has a first end operably connected 72 to the cathode of the first diode as well as a second end operably connected to ground. The first and second current paths are operably connected between the first and second capacitors and include a second diode, a parallel combination of a first resistor R1 and a third diode D3, and a second resistor R2. The first diode is operably connected in parallel with the first capacitor. The second resistor has a first end operably connected to the cathode of the first diode and the parallel combination is operably connected between a second end of the second resistor and the first end of the first capacitor.
