The invention discloses an AC power load intelligent controller, which comprises an AC commercial power, a step-down rectifier module, an overvoltage protection module, an under-voltage protection module, a control module and an alternating-current load. The input end of the step-down rectifier module is connected with the AC commercial power. The output end of the step-down rectifier module is respectively connected with the overvoltage protection module and the under-voltage protection module. The overvoltage protection module and an over-current protection module are simultaneously connected with the control module. The control module is also respectively connected with the AC commercial power and a load. According to the invention, a complex chip structure is not adopted by the above circuit, while the monitoring protection for the over-voltage condition and the over-current condition of a household power grid can be realized based on the combination of simple electronic components. Not only the circuit structure is simplified, but also the manufacturing cost is reduced. The chip-free structure is relatively better in interference resistance, so that the circuit has the advantages of simple structure, low manufacturing cost, and stable operation. The AC power load intelligent controller can normally work under the environment of the electromagnetic interference and is very suitable for popularization and use.
