| Zusammenfassung: | The present invention provides an electronic capacitance voltage division mutual inductor temperature compensation method and device. The method comprises the following steps: respectively detecting the temperatures of a high-voltage arm capacitor and a low-voltage arm capacitor of the electronic capacitance voltage division mutual inductor; calculating the real-time voltage division ratio K' of the electronic capacitance voltage division mutual inductor at the current temperature; performing compensation of the voltage division signals U' collected by the electronic capacitance voltage division mutual inductor according to the obtained real-time voltage division ratio K' and the standard voltage division ratio K of the electronic capacitance voltage division mutual inductor, and obtaining voltage division signals U after temperature compensation; and performing conversion and output of the voltage division signals U after temperature compensation. According to the technical scheme of the invention, the elect |
