Ammeter-Resistor Operation and How to Choose the Right One for Renewable Energy

Ammeter-Resistor Operation and How to Choose the Right One for Renewable Energy

Ammeter resistors are put back in the spotlight as the rise of renewable energy. The increase in the number of solar, wind, wave, and tidal power sources has pushed the need for a highly accurate method of measuring current. The solution is required for several reasons: to ensure accurate billing, have a more granular level of control, and, perhaps most importantly, to ensure the efficiency of the distributed power system. There are a few ways to measure current. However, the one most suited for renewable applications looks t...

Shunt Resistor in Battery Management System (BMS)

Shunt Resistor in Battery Management System (BMS)

A shunt resistor and magnetic current sensor are used to measure the voltage drop flowing through. It is said the intelligence of the battery does not lie in the cell but in the complex battery system. In todays automotive applications, above two current sensing technologies is generally used. The Shunt resistor is more accurate and less costly than the Hall Effect current-sensing solution, while the tapped holes assist in the PCB placement process, providing additional vibration immunity and the location of the fixed voltage...

How does a Chip Resistance Testing Equipment Helps to Improve the Product Quality?

How does a Chip Resistance Testing Equipment Helps to Improve the Product Quality?

After all the process of chip resistance manufacture, packing will be carried out and placed on the carrying belt to form a strip. In the packaging, there will be some phenomena such as fragmentation, mixing, setting-up, inversion, placing, empty material, jumping material, material missing angle, carrying belt contamination, carrying belt damage, and so on. A bad resistance flowing to the client terminal and attached to the circuit board will result in the bad quality of the final product, and a security risk. Because of a b...

Why Current Sensing Resistors are Widely Used in Automotive Electronics and Home Appliance?

Why Current Sensing Resistors are Widely Used in Automotive Electronics and Home Appliance?

Current sensing resistor, including shunt resistor, is very popular for their high power, low resistance and low inductance. It is conducive to control the noise for high frequency and high speed application. And because of the inverted structure and long edge, the power dissipation ability is improved. The rated power of the current sensing resistor indicates the maximum energy that the resistor can consume without damage or degradation. Most manufacturers say their free air flow is rated at 70 C. Above this temperature, the...
