A simple and reliable circuit breaker specially designed for modern DC power systems (like solar micro-grids). It uses smart timing and energy storage to quickly isolate faults and automatically try restarting, all without extra sensors. Computer tests show it can protect power lines in both directions and keep the lights on wherever possible.

In modern energy systems, especially those using solar or battery-based power (DC micro-grids), protecting the system from short circuits or faults is very challenging. Traditional circuit breakers used in homes or industries are not well suited for these DC systems because they struggle to detect or respond quickly to sudden faults. If not handled properly, such faults can damage equipment or interrupt power supply.
- Pre-Charged Rapid Response: This product pre-charges its internal capacitor so it can immediately cut off a fault, even while trying to reconnect.
- Timed Switch Coordination: This feature uses controlled delays between switches to manage energy without complex fault-sensing electronics.
- True Bidirectional Operation: This design works both when power flows forward or in reverse, ideal for two-way DC systems.
- Auto-Reclosing Capability: This product automatically recloses after a fault, reducing downtime without manual resets.
- Coupled Inductor Efficiency: This feature employs coupled inductors to simplify wiring and improve efficiency.
The breaker exists as detailed computer models built in MATLAB. The team created virtual circuits that mimic real-world conditions, tested fault scenarios, and refined timing controls. Prototype is designed to validate the breaker functionalities.
The technology has been developed up to a simulation level using software tools. It has been tested under various fault conditions virtually and on hardware prototype to check how well it performs.

By dramatically enhancing both safety and reliability in renewable energy installations, this advanced circuit breaker can play a pivotal role in empowering rural and off-grid communities. Its rapid fault isolation and automatic reclosing capabilities minimize the frequency and duration of power interruptions translating into fewer blackouts for households and critical services alike. With less wear and tear on equipment, maintenance demands and associated costs drop significantly, freeing up local resources for other development needs. Steadier, more predictable power delivery supports continuous operation of schools, healthcare clinics, small businesses, and agricultural systems, fostering economic growth, improving educational outcomes, and ensuring that vital medical equipment remains operational when it’s needed most.
