Claims
- 1. The method of controlling a cooking system having an electrical heating element submerged in a cooking oil, and the triac power switching means for controlling alternating circuit power to the heating element which switch power at zero voltage during zero voltage crossover comprising duty cycle modulating power to a heating elements by switching the triac power switching means at a duty cycle rate substantially less than the thermal time constant of the heating element to maintain a substantially constant temperature at the surface of the heating element in contact with the cooking oil.
- 2. The method of claim 1 wherein the power is duty cycle modulated at a constant fractional power rate substantially less then maximum power from initial start up until substantially the set point cooking temperature is reached.
- 3. The method of claims 1 or 2 wherein the power is duty cycle modulated to maintain the cooking oil at a set point temperature without material overshoot during cooking cycles by proportionally modulating the power in a preselected temperature band below the setpoint temperature.
