Abstract
Gas cooktops disclosed herein may include a proportional solenoid valve controlling gas flow to a gas burner, where the proportional solenoid valve has a continuously variable range of positions. A user interface (UI) element associated with the proportional solenoid valve may be utilized to control a linear voltage regulator having a continuously variable output voltage. The output voltage of the linear voltage regulator is coupled to a solenoid of the proportional solenoid valve, such that the gas flow to the gas burner has a linear relationship with the output voltage of the linear voltage regulator.
