  • Patent number: 8680440
    Abstract: A control circuit and associated method for dynamically controlling power to one or more heating elements are provided. A power source supplies power to a load through one or more current pass elements, which is controlled by a control signal. A processor determines a time period (T) having a time cycle beginning at Ton and a Time cycle end at Toff, where the Time cycle end is less than the time period (T), variable, and generates the control signal or signals each time period (T), thereby electrically connecting the power source to the load and the current sensing element each time period (T) to dispense precisely predetermined quantities of energy per pulse.
