The max shunt voltage is chosen as ±80mV. Assume the max measured current is ±100A. The shunt (sense) resistor value is calculated using Equation 1. Equation 1: Using Ohm's Law to calculate the Shunt ...

Conclusion Hall-effect sensors are emerging as the preferred devices for accurate, stable current measurements in high-voltage systems. TI’s TMCS1123 offers a 75-A continuous current rating and ...

Littelfuse launched its new SSA Series current shunt resistors for accurate current measurement in high-performance applications. Littelfuse says "Unlike competing technologies such as Hall effect ...

ST’s New Current-Measurement Preamp Addressing the needs of low-side sensing, the TSC1801 from STMicroelectronics (ST) current-measurement amplifier integrates matched resistors to set the gain ...

From a current perspective, anything below 100 A tends to be a shunt-based solution. Between 100 A and 500 A, choosing between a shunt or magnetic solution requires trade-offs between cost, ...

Below are a couple of shunt-resistor-based and Hall-effect current sensor-based bridgeless totem-pole PFC design examples. 4-kW Single-Phase Totem-Pole PFC Reference Design with C2000™ and GaN 3.6-kW ...
