Rapid gas ignition system

A method for controlling energizing of a gas burner with an electrical resistance igniter in a control system for a gas powered appliance, the method comprising:

• receiving a signal in a timer circuit from a control interface of the gas powered appliance when the control interface is in an on position;
• providing power from a first direct current power supply to the electrical resistance igniter through activation of a boost circuit, wherein the timer circuit activates the boost circuit for a predetermined period of time;
• and
• after expiration of the predetermined period of time, deactivating the boost circuit and switching the power provided to the electrical resistance igniter from the first direct current power supply to a second direct current power supply to maintain the electrical resistance igniter at a predetermined temperature above an ignition temperature of the fuel, wherein a voltage provided by the second direct current power supply is less than a voltage supplied by the first direct current power supply,
• wherein the on position of the control interface activates the first direct current power supply to energize the boost circuit and a second position of the control interface modulates a flow of fuel to the gas burner with the second direct current power supply in an activated state.

A gas cooking appliance comprising an ignition control system, a burner, a user actuatable valve for controlling a flow of fuel to the burner, the user actuatable valve being movable between an off state and an on state and an electrical resistance igniter for igniting fuel at the burner, wherein the ignition control system comprises:

• a control interface coupled to the valve;
• a control board including a boost circuit and a timer circuit, the timer circuit being coupled to the boost circuit and the control interface, the control interface being configured to communicate a control signal to the timer circuit for activation of the boost circuit for a predetermined period of time;
• a first direct current power supply coupled to the boost circuit and the electrical resistance igniter, where power from the first direct current power supply is provided to the electrical resistance igniter through the boost circuit during the predetermined period of time;
• and
• a second direct current power supply coupled to the electrical resistance igniter and the control interface, the second direct current power supply being configured to provide power to the electrical resistance igniter after expiration of the predetermined period of time to maintain the igniter at a predetermined temperature above an ignition temperature of the fuel, wherein a voltage from the first direct current power supply is greater than a voltage from the second direct current power supply,
• wherein the control interface comprises a gas control knob, a first position of the gas control knob activating the first direct current power supply to energize the boost circuit and a second position of the gas control knob modulating the flow of fuel to the burner with the second direct current power supply in an activated state.
