How To Choose Between Hall Effect Current Sensor And Shunt Resistor
Hall effect current sensors and shunt resistors are both useful current measurement solutions, but they serve different design needs. Hall effect sensors are better for isolated, high-current, AC/DC, bidirectional, and safety-sensitive applications. Shunt resistors are better for compact, low-cost, low-voltage, and simple DC current measurement when power loss and heat are acceptable. For EV chargers, BESS, solar inverters, motor drives, UPS systems, welding machines, and industrial power electronics, the final choice should consider isolation, current range, accuracy, drift, response time, power loss, heat, installation space, output signal, safety, and total system cost. The best current measurement method is the one that fits the complete application, not just the lowest component price.
