Where are power converters used in Smart Substation? They are mainly used in monitoring and protection device for detection and prote ction. In most applications, AC/DC converters and DC/DC converters are used for power conversion and signal isolation, to offer an isolated and stable voltage to the control circuit.

Power converters in monitoring and protection devices in electric power systems are needed to convert the mains supply to lower DC voltage to drive the control circuit, so isolation and reliability of the converters are significant for the safety of the control unit. Also, signal isolation is very important to suppress interference and realize clean signal output for error detection and protection.
