Description

technical field [0001] The invention belongs to the technical field of power measurement and information equipment, and in particular relates to a multi-dimensional compensation intelligent shunt. Background technique [0002] A shunt is a sensing device for measuring DC current. In the field of DC large current measurement technology, high-power shunts are widely used for measurement. A high-power shunt is mainly composed of a low-value resistor. According to Ohm's theorem, when a DC current flows through the shunt, a voltage drop occurs across the shunt resistor. By measuring the voltage drop across the shunt resistor, the current value can be calculated. Due to the advantages of simple structure, reliable operation, stable performance and low cost, high-power shunts are widely used in electric vehicles, high-power chargers, high-power rectifiers, high-power inverters, communication base station backup batteries, battery energy storage, etc. Field DC current measurements....
