摘要: A microprocessor-controlled triac switching circuit for an igniter, having line voltage and igniter current input signals to a microprocessor for determining power to the igniter. Upon determining the line voltage, the microprocessor selects from a look-up table a corresponding triac-switching sequence intended to drive the igniter to a power level proven to ignite gas. The igniter current resulting from the switching sequence is fed to the microprocessor, which determines the actual power and an offset value. The offset enables adjustment by shifting sequences, to achieve the pose level at which the igniter is proven to ignite gas.
