Replacement of a 100-year old technological dinosaur
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. In the past technology availability and cost limited solid-state implementations to niche applications. Infineon´s new and advanced power semiconductors enable cost efficient and reliable solutions on a broad scale.
A smart solid-state circuit breaker integrates advanced functionality into one single device:
- Combines protection, actuation, load control, diagnostic, metering and secure communication
- AC and DC agnostic
- Offers secure web/IoT connectivity
- Captures and logs data in real time
- Enables smart power balancing and control of peak loads
- Detects and isolates faults in sub µs range
Customer benefits
- Provides noise-less and wear-free load switching with real-time control capability
- Enables remote load control and diagnostic in real time
- Provides highly accurate and user programmable tripping characteristics
- Supports smart billing, even for sub-branches
- Provides state-of-health diagnostics of connected loads
Product offering includes all system needs: from sense – compute – actuate to the next level of connectivity and security
Our product portfolio for solid-state circuit breakers 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.
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 CoolSET™ 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.
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, SEMPER™ 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 AIROC™ Bluetooth devices.
Efficient kit for AC-DC solid state circuit breaker evaluation
This fully featured evaluation kit with an interactive GUI supports quick and efficient evaluation of solid-state circuit breaker application up to 230 VAC resp. 350 VDC at 16 A nominal current. All aspects of a smart circuit breaker are included and ready for assessment: protection, measurement, programmability, communication and actuation.
As the world moves towards a more sustainable future, renewable energy sources are becoming increasingly popular, despite being less predictable. As the adoption of electric vehicles increases, so does the need for peak power to keep them charged and on the road.
To manage these challenges, we need smart power distribution down to the single sub-branches so that energy needs are always met.
