What makes it different? Traditionally, most buildings use Alternating Current (AC). This tool helps explore DC infrastructure by offering quick design and operation simulations, as well as comparisons with AC.
Key Advantages:
✅ Electrical Sizing: It helps determine the right sizes for cables and converters, optimizing the system’s operational efficiency based on given scenarios.
✅ Simulating “Load Flow” and power losses: It estimates how electricity flows through the network under real-world conditions.
✅ Performance Comparison (KPIs): It generates Key Performance Indicators to show exactly how a DC setup performs compared to a standard AC setup.
✅ Operational Testing of droop-controlled setup: Integrates the possibility of simulating devices with internal voltage droop control to assess how the network responds to changes in power balance.

What makes it different?
Semiconductor-based circuit breakers are designed specifically for the challenges of #DC power systems, where fault currents rise rapidly and no natural current zero crossing exists. Solid-State Circuit Breakers (SSCBs) interrupt faults electronically within microseconds, while Semiconductor Hybrid Circuit Breakers (SCHCBs) combine semiconductor switching with low-loss mechanical contacts to achieve both fast protection and high efficiency.
✔️ Within #Shift2DC, these technologies are being integrated into coordinated protection architectures for reliable, resilient and scalable LVDC grids.
Key Advantages:
✅ Ultra-fast protection: Fault interruption from microseconds to the sub-millisecond range, depending on the breaker technology.
✅ Smart protection: Integrated monitoring, configurable trip settings, pre-charge, intertripping and digital communication.
✅ Designed for LVDC: Reliable interruption despite fast-rising fault currents and the absence of natural current zero crossings, with current ratings from 20 A to 100 A, 2-pole full protection, bidirectional operation and each pole sized for 800 V.
✅ Selective isolation: Coordinated breakers safely disconnect the affected branch, provide safe galvanic isolation and maintain operation of healthy grid sections.
✅ Scalable architectures: SSCBs, hybrid breakers and mechanical breakers can be combined according to application requirements.
