The invention relates to an
electric heating controller and a control method thereof. The
electric heating controller comprises an
electric heating part, a switch circuit and a drive circuit, and is characterized by further comprising a low-
voltage detection circuit and a main control
chip MCU (microprogrammed
control unit), wherein the switch circuit is used for controlling switching on-off of an
alternating current power supply, the drive circuit is arranged on the switch circuit, and the main control
chip MCU is at least provided with a
timer. The control method of the electric heating controller comprises the following steps of: quickly carrying out switching on-off control of an electric heating part during a shorter period to realize regulation of
heating power of the electric heating part; and simultaneously, preventing a
flicker effect of a lighting device caused by instant and quick change of power of the electric heating part by utilizing a soft-start and soft-switching-off gradual-change power regulating method in an initial stage and a finishing stage for controlling the switching on-off, and also avoiding uncomfortableness of a user on light change. According to the invention, infinite
power regulation can be realized, the comfortable experience of the user is improved, dissipation power of heating of the switch circuit is less compared with that in a chopping scheme, simultaneously a
flicker problem is effectively avoided by utilizing soft starting and
soft switching-off, and practical application effect is good.
