[0027] (1) The power conversion circuit includes PMOS transistor G1, PMOS transistor G2, resistor R1, resistor R2, resistor R3, resistor R4, resistor R6 and resistor R7, wherein the gate voltage of PMOS transistor G1 is (where U is the external input voltage), the source voltage of PMOS is U, and the gate-source voltage When full (VGS is the conduction voltage parameter value of G1), the PMOS transistor G1 is turned on. Similarly, it can be known that the conduction voltage of the PMOS transistor G2 is when , the PMOS tube G2 is turned on.

[0028] We choose a PMOS tube with a VGS of about -2V, and select a suitable resistor to make the voltage input low, so that the PMOS tube G2 is turned on (wherein, the voltage design starts at 2.8V). When the PMOS transistor G1 is turned on, after the PMOS transistor G1 is turned on, the gate of the PMOS transistor G2 rises, and the PMOS transistor G2 is cut off quickly. When the PMOS transistor G1 is turned off, when the voltage...

Abstract

The invention discloses an aluminum electrolysis cell voltage collector, which comprises a power conversion circuit, an energy storage power supply, an automatic conversion data acquisition module, a conversion point de-jitter circuit and a temperature compensation circuit, and is characterized in that the power conversion circuit comprises a PMOS tube G1, a PMOS tube G2, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R6 and a resistor R7, and the voltage at the two ends of the resistor R1 and the resistor R2 is 2.8-100V; according to the invention, the automatic conversion data acquisition module is adopted, so that automatic acquisition of data in the aluminum electrolysis cell voltage collector is realized; due to the arrangement of the conversion point jitter removing circuit, the oscillation phenomenon that the PMOS transistor G1 is changed from conduction to cut-off and then changed from cut-off to conduction caused by voltage jitter of the electrolytic bath can be effectively restrained. Wherein the temperature compensation circuit is arranged, so that the influence of the environment temperature on the work of the device can be effectively avoided, and the measurement precision is ensured.
