Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0016] like figure 1 As shown, the temperature-compensated power supply of the present invention is mainly composed of a DC power supply S, a control circuit connected to the DC power supply S, a temperature compensation circuit connected to the control circuit, and a phase compensation circuit connected to the temperature compensation circuit. The connected photoresistor CDS is composed of a beam-excited logic amplifier circuit connected in series between the DC power supply S and the photoresistor CDS. At the same time, a trilinear buffer drive circuit is connected in series between the DC power supply S and the photoresistor CDS.

[0017] Wherein, the control circuit is composed of a transistor Q1, a transistor Q2, a resistor R1, a resistor R2, a resistor R5 and an RC...

Abstract

The invention discloses a temperature compensation type logic amplification power supply device. The temperature compensation type logic amplification power supply device is characterized in that the device is mainly composed of a direct-current power supply S, a control circuit connected with the direct-current power supply S, a temperature compensation circuit connected with the control circuit and a light dependent resistor CDS connected with the temperature compensation circuit; a light beam excitation type logic amplification circuit is connected between the direct-current power supply S and the light dependent resistor CDS in series. The device is simple in overall structure and very convenient to manufacture and use. Meanwhile, an output current value can be automatically adjusted according to the temperature change of external environment, signals amplified by a power amplification circuit cannot be attenuated greatly, and therefore the quality and performance of the amplified signals can be ensured, it is ensured that the performance of the amplified signals is more stable, radio-frequency interference of the circuits and the outside is effectively lowered, and it is ensured the performance is stable.

Description

technical field [0001] The invention relates to a power supply device, in particular to a trilinear buffer driving amplifying power supply device. Background technique [0002] At present, after making the battery protection circuit board, 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, that is, to use the bipolar power supply to quickly realize the protection of the battery protection circuit board. Rapid 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...
