Embodiment Construction
[0034] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.
[0035] The invention provides a novel intelligent electronic coil, such as figure 1 As shown, it includes: a micro-power consumption processor M, a full-bridge rectifier circuit 1, an excitation coil C, a first switch tube K1 and a freewheeling demagnetization circuit 2; the first input of the micro-power consumption processor M terminal is connected to the output terminal of the voltage sampling circuit A, and the voltage sampling circuit A is used to sample the instantaneous value of the input voltage to ensure that the excitation coil C starts reliably, and provides the sampling voltage required for calculating the average value of the input voltage during the breaking process to ensure that The excitation coil C is reliably disconnected; the input terminal of the voltage sampling circuit A is connected to the first output terminal of ...
