Solid-state circuit breaker

Replacement of a 100-year old technology

nobutton

Overview

Electro-mechanical circuit breakers were developed a 100 years ago. Now it is time for a smart, intelligent solid-state device. While conventional electro-mechanical components exhibit performance limitations, solid-state solutions unleash unprecedented control and protection capabilities. The advanced power semiconductors enable cost efficient and reliable solutions on a broad scale and integrates advanced functionality into one single device.

Benefits

  • AC and DC agnostic
  • Offers secure web/IoT connectivity
  • Captures and logs data in real time
  • Smart power balancing
  • Enables control of peak loads
  • Isolates faults in sub ?s range

About

From sense ¨C compute ¨C actuate to the next level of connectivity

Our product portfolio for solid-state circuit breakers, which combine protection, actuation, load control, diagnostic, metering and secure communication in one, ranges from power switches and corresponding gate drivers to sensors, microcontrollers, memories, communication and security devices. This supports seamless system integration in combination with wide power range and feature scaling capability.

Key components of a smart circuit breaker

Depending on the system voltage resp. system current ratings a broad portfolio of Power MOSFETs as discrete devices or in module packages can be chosen.?

Matching isolated/non-isolated gate drivers complete the power device portfolio for solid state circuit breakers. Used to measure both AC and/or DC currents, Infineon¡¯s XENSIV? - high-precision coreless current sensors provide accurate and stable current measurement.

The latest iteration of fixed frequency flyback controller and CoolSETTM offers a high level of integration with enhanced and comprehensive suite of protection. ISOFACE? dual- and quad-channel digital isolators provide robust high-voltage isolation with precise timing and low power consumption.

Key components of a smart circuit breaker

For remote control, diagnostics, monitoring, and maintenance purposes, discover Infineon¡¯s 32-bit industrial microcontroller XMC? family or PSoC family. Take a look at Infineon¡¯s wide range of volatile and non-volatile memories, including types such as SRAM, SEMPERTM Secure NOR Flash, F-RAM or non-volatile SRAM to complement system microcontrollers.

For one of the best-embedded security products on the market, choose the OPTIGA? Trust product family. And consider Infineon¡¯s USB or Wi-Fi controllers to meet the latest IoT networking needs. To minimize galvanic isolation efforts, circuit breakers communicate with all other systems compensation the control cabinet via our AIROCTM Bluetooth devices.
