Abstract
Disclosed is a control strategy for a hot surface igniter. On the basis of a hardware circuit of the hot surface igniter and a software algorithm, a working time of the hot surface igniter is divided into t1, t2, . . . , and tn time periods. In each time period, an output voltage or an output power of the hardware circuit is adjusted by the software algorithm to make the hot surface igniter reach an expected temperature. Through the control strategy of the disclosure, ignition time of the hot surface igniter may be easily controlled. The requirements of a user of igniting in a short time are satisfied.
