Low voltage power supply for spark igniter and flame sense |
摘要 |
A low voltage power supply circuit for intermittent pilot and/or direct spark ignition systems utilized in gas burning appliances is provided. The circuit utilizes a single transformer and a resonant circuit to supply power to both a flame sense circuit as well as the spark generation circuit. The resonant circuit allows the use of low power sources such as batteries or self-supplied voltage systems such as thermopiles or hydro generators. Recognizing that power draw from the low power source is high during a sparking event and recharging of a sparking capacitor, the flame sensing is suspended during the sparking event and for a short recharge time thereafter.
