WebIntroduction. It can be challenging to sense currents exceeding 50 A because the task often involves thermal management, must take place in a limited PCB area, and in some cases, requires a voltage isolation device. Two widely used methods for sensing high currents are a sense-resistor/op-amp approach, and Hall-based current sensing. WebEnergy transmission by high voltage direct current - HVDC - is steadily increasing in the world, both at the highest power levels, but also at medium power, for example in connections of remote wind-
