LOAD DETECTION METHOD, LOAD DETECTION CIRCUIT AND ELECTRONIC DEVICE

摘要

Provided are a load detection method, a load detection circuit and an electronic device, which relate to the technical field of load detection. The load detection method is applied to a load loop, the load loop comprises a thyristor module (42) and a load (43), and the thyristor module (42) is connected to the load (43) in series. A load detection method (60) comprises: determining an operating mode of a load (43) (61); according to the operating mode of the load (43), sampling a current detection signal flowing through the load (43) (62), wherein an operating state of a thyristor module (42) comprises a conductive period or a cut-off period, the current detection signal comprises a first alternating-current signal or a second alternating-current signal, the first alternating-current signal is acquired by sampling when the operating state of the thyristor module (42) is the conductive period, and the second alternating-current signal is acquired by sampling when the operating state of the thyristor module (42) is the cut-off period; and according to the current detection signal and the operating state of the thyristor module (42), determining an operating state of a load loop(63). By means of the method, corresponding load detection control logic can be flexibly configured according to an operating mode of a load.
