The invention discloses a method and a device for improving the interference rejection of an electric board in electric equipment. The method comprises the following steps: sampling an input voltage of the electric board; judging whether the electric board is in a voltage sag or short interruption state according to the input voltage of the electric board; and if the electric board is in the voltage sag or short interruption state, turning off a load associated with the electric board in the electric equipment, to prolong the running time of the electric equipment before the electric board is reset. According to the method, the input voltage of the electric board is sampled, whether the electric board is in the voltage sag or short interruption state is judged according to the input voltage of the electric board, and if so, the load associated with the electric board in the electric equipment is turned off to prolong the running time of the electric equipment before the electric board is reset, so that the circuit board is not crashed or reset due to too low voltage; and the method greatly improves the interference rejection of the electric board to voltage sag or short interruption.
Description
technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a method and a device for improving the anti-interference degree of an electric control board in electrical equipment. Background technique [0002] The electronic control boards of household / commercial appliances have certain requirements on the immunity of voltage dips and short interruptions. Before the products are launched on the market, they need to pass the test of immunity to voltage dips and short interruptions. Although different manufacturers require different immunity to voltage sags and short interruptions for different products, they will try their best to improve the immunity of products at the same cost to improve product quality. [0003] In the national standard for immunity tests of voltage sags, short interruptions and voltage changes, it is recommended to classify according to the following requirements for the evaluation of test results: [00...
