Current transducers are electrical devices used to measure and quantify electrical current through primary current inputs (AC, DC, or pulse) and then pass these readings as secondary signals, usually for monitoring or control purposes. The SI8513-C-IMR is a current transducer, specifically designed for the power electronics market, to ensure a reliable performance in the harshest industrial environments. This article will describe the application fields and working principles of SI8513-C-IMR.

Overview of SI8513-C-IMR

The SI8513-C-IMR is a third-generation, three-phase current transformer, intended for the power electronics market. It has a single monolithic magnetic core with standard sense current inputs. Its on-board ASIC controller, internal linear regulator, and ESD protection system enable the SI8513-C-IMR to produce very accurate outputs with high isolation characteristics. This allows it to be used in the most demanding industrial applications.

Application Fields of SI8513-C-IMR

The SI8513-C-IMR can be used for a wide variety of industrial applications requiring fast, accurate readings of AC, DC, and pulse currents. These include motor drives, inverter motor controls, monitoring and control systems, and power converter applications. This device can be used in both AC and DC power systems with a wide range of primary current. It is also suitable for applications requiring a wide range of environmental temperatures and working voltages, making it suitable for applications in extreme climates.

The SI8513-C-IMR can also be used in a wide range of safety-related applications due to its high insulation characteristics and linear response. Examples of safety-related applications are EMC (electromagnetic compatibility) compliance testing, personal safety monitoring, and ground fault protection systems.

Working Principle of SI8513-C-IMR

The SI8513-C-IMR current transducer is based on a magnetic core principle that uses a single monolithic core. This core is made from a high-permeability material and contains a single size of winding for each phase of the primary current signal. The measured primary current signals across the magnetic core will create a mutually coupled and spatially proportional magnetic flux, which will induce a corresponding voltage across the secondary winding.

The output of the SI8513-C-IMR is a linear voltage, that is proportional to the primary current. A special ASIC controller, which is integrated into the device, ensures reliable performance and high accuracy across a wide range of primary currents. This device also has an internal linear voltage regulator, which provides a consistent power supply to the device, ensuring that the readings remain stable over time. Finally, an ESD protection system is integrated into the device, ensuring that it can work in the presence of strong electromagnetic fields.

Conclusion

The SI8513-C-IMR is a current transducer, specifically designed for the power electronics market, to ensure a reliable performance in the harshest industrial environments. This device can be used in a variety of applications, thanks to its wide range of primary current inputs, linear response, and high insulation characteristics. Finally, its integrated ASIC controller, linear voltage regulator, and ESD protection system ensure that it delivers accurate and reliable readings in almost any environment.
