Circuit breaker energy storage release

What is a solid-state circuit breaker (ABB)?

A technological breakthrough by ABB – a solid-state circuit breaker – will enhance performance of renewable energy solutions, industrial battery storage solutions and so-called edge grids.

How does a solid-state breaker work?

The ABB solid-state breaker concept works by replacing the traditional moving parts of an electro-mechanical circuit breaker with power electronics and advanced software algorithms that control the power and can interrupt extreme currents faster than ever before.

Why is a solid-state circuit breaker important?

Energy efficiency is a crucial aspect for all electrical installations, including those operating on islanded grids such as vessels with an onboard DC grid. Compared to other semiconductor technologies, ABB’s solid-state circuit breaker guarantees 70% less power losses during the conduction phase.

How are solid-state circuit breakers classified?

First, we categorize solid-state circuit breakers based on key features and subsystems, including power semiconductor devices, main circuit topologies, voltage clamping methods, gate drivers, fault detection methods, and commutation methods for power semiconductor devices.

How fast can a solid state circuit breaker detect a short circuit?

ABB’s solid-state circuit breaker can detect and respond to a short circuit fault 100 times faster than a mechanical circuit breaker. Energy storage systems and their corresponding electrical grid services are strongly affected by the downtime in case of an internal fault.

Can 21st century circuit breaker technology meet the demands of renewables?

Our 21 st Century circuit breaker technology can better meet the demands of renewables, the electrification of transport and modern edge grids as today`s offerings,” said Giampiero Frisio, the head of ABB’s Smart Power business line.
