Abstract

A method to limit ozone production in wind ion devices while simultaneously realizing incidents of high acceleration in such devices varies the high voltage potential across the array of emitter(s) (10) and collectors (20) ov er time in such a manner as to generate a wave effect of airflow. The variance may be achieved by switching, ramping, or gating the high voltage potential delivered to the array.

Claims (10)

1. A method of reducing ozone production in ion wind devices, said method comprising the steps of:
providing an emitter;
providing a plurality of collectors;
positioning said collectors generally equidistant from said emitter to form an array;
providing a high voltage potential between said emitter and said collectors;
and varying said high voltage potential over time to generate a wave effect of airflow and reduce total ozone production.
2. The method of reducing ozone production in ion wind devices of claim 1 wherein said step of varying said high voltage potential over time comprises switching said high voltage potential from a lower high voltage level for a first period of time, to a higher high voltage potential for a second period of time.
3. The method of reducing ozone production in ion wind devices of claim 2 wherein said lower high voltage level is approximately +6 KV, and said higher high voltage potential is approximately +8.5 KV.
4. The method of reducing ozone production in ion wind devices of claim 2 wherein said first period of time is greater than said second period of time.
5. The method of reducing ozone production in ion wind devices of claim 4 wherein said first period of time is approximately 3 seconds, and said second period of time is approximately 1 second.
6. The method of reducing ozone production in ion wind devices of claim 1 wherein said step of varying said high voltage potential over time comprises providing a nonlinear ramp driving voltage to said emitter/collector array.
7. The method of reducing ozone production in ion wind devices of claim 6 wherein said nonlinear ramp driving voltage has a duration of approximately 4 seconds.
8. The method of reducing ozone production in ion wind devices of claim 6 wherein said nonlinear ramp driving voltage has an ending portion and trailing edge effecting the highest voltage state for approximately 1 second.
9. The method of reducing ozone production in ion wind devices of claim 1 wherein said step of varying said high voltage potential over time comprises providing a gating voltage to said emitter/collector away.
10. The method of reducing ozone production in ion wind devices of claim 9 wherein said gating voltage is turned from a zero state to a maximum high state at predetermined time intervals.
