Device to provide a regulated power supply for in-cylinder ionization detection by using the ignition coil fly back energy and two-stage regulation |
摘要 |
The present invention is directed to a dual charge rate power supply circuit and method for ionization detection. The circuit includes a first diode, first and second capacitors, and first and second current paths. The first diode includes an anode operably connected to a first end of a primary winding. The first capacitor has a second end operably connected to ground and the second capacitor has a first end operably connected 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 and a third diode, and a second resistor. 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.
