Abstract

The invention discloses an emitter coupling type asymmetric bipolar logic amplifier power supply device which mainly comprises a direct-current power supply S, a diode D1 and an electronic switch K, wherein the P pole of the diode D1 is connected with the positive pole of the direct-current power supply S, the N pole of the diode D1 passes a load resistor and then forms a circuit with the negative pole of the direct-current power supply S, and the electronic switch K is connected with the diode D1 in parallel. The emitter coupling type asymmetric bipolar logic amplifier power supply device is characterized in that passive pi type filter circuits and emitter coupling type asymmetric circuits are connected between the N pole of the diode D1 and the negative pole of the direct-current power supply S in series, and the emitter coupling type asymmetric circuits are connected with the passive pi type filter circuits; meanwhile, beam stimulation type logic amplifier circuits are connected between the emitter coupling type asymmetric circuits and the direct-current power supply S in series. The multiple stages of filter circuits and the logic amplifier circuits are included so that multiple harmonics caused by load changes can be effectively removed, detection accuracy can be guaranteed, it can also be guaranteed that signals amplified through the device can not attenuate greatly, and the quality and the performance of the amplified signals can be guaranteed.

Description

technical field [0001] The invention relates to a bipolar power supply device, in particular to an emitter-coupled asymmetrical bipolar power supply for testing and calibrating the function of a battery protection circuit board. Background technique [0002] At present, battery manufacturers generally need to use a bipolar power supply to detect whether the functions of the battery protection circuit board have reached the standard after making the battery protection circuit board. Quick calibration and testing of overvoltage, undervoltage and overcurrent. The so-called bipolar power supply means that when the power supply is discharged, the current inside the power supply flows from the negative pole to the positive pole, and when the power supply is charged, the current inside the power supply flows from the positive pole to the negative pole (the internal current of the traditional common power supply no matter whether it is In any case, it can only flow from the negativ...
