Aerospace Inverter Hall Current Sensors Price – Vicorv

58彩票A current sensor is an electrical device used to measure the current along a specific wire. Inverter Hall current sensors achieve this by measuring the voltage drop across a resistor in the current path. This allows the sensor to estimate the level of current flowing through the line. The output of the current sensor can either be a voltage reading or a continuous current, which is roughly proportional to the current level moving along the test path.

There are various types of current sensors available to monitor AC or DC currents, and these are needed in many applications across industrial, automotive, or household fields. A current sensor detects and converts current to obtain an output voltage, which is proportional to the current in the designed path. When current flows through a circuit, the voltage drops along the path through which the current flows. Additionally, a magnetic field is generated near the current-carrying conductor. These phenomena are utilized in the design techniques of current sensors.

To minimize power loss, the value must be kept low: the value of current sensing is usually dependent on the threshold voltage of the circuit. The operation of inverter Hall current sensors is entirely based on the sensed current information. To improve accuracy, we must consider a low-temperature coefficient: in terms of accuracy, temperature is a major coefficient of resistance. A resistor with a temperature coefficient close to zero should be used throughout the operation. The power derating curve provides the allowable power at different temperatures. However, the peak power capacity is a function of energy, so the energy rating curve should be considered. Introducing additional resistance in the measured circuit path may increase the source output resistance, producing undesirable load effects. Due to the direction of power dissipation, power loss occurs. Therefore, current-sensing resistors are rarely used outside of low and medium current-sensing applications.

有各种各样的电流传感器来监测交流或直流电流，在工业、汽车或家庭领域的许多应用中都需要对其进行测量。电流传感器是一种检测和转换电流以获得输出电压的装置，输出电压与设计路径中的电流成正比。当电流通过电路时，电压会在电流流过的路径上下降。此外，在载流导体附近产生磁场。这些现象被用于电流传感器的设计技术中。

为了将功率损耗降至，值必须取低：当前感测的值通常取决于电路的阈值电压，逆变器霍尔电流传感器操作完全基于感测的电流信息。为了提高精度，我们必须考虑低温系数：就精度而言，温度是电阻的主要系数。一种电阻，其温度系数电阻接近于零，在整个操作过程中应使用。功率降额曲线提供不同温度下的允许功率。但峰值功率容量是能量的函数，因此应考虑能量额定曲线。在被测电路路径中引入附加电阻，可能增加源输出电阻，产生不良的负载效应。由于功率耗散的方向，功率损失。因此，电流传感电阻器很少用于低电流和中等电流传感应用之外。
