| Abstract: | Current sampling is one of the key problems in the design of power circuits. Based on different circuit design, three methods for current sampling are discussed. Their principles, the physical implementation of sampling sensors, and application examples in the circuit design are dealt with. Finally, these techniques are compared for their advantages and disadvantages. |
