Latest Patents

Risha Na holds a patent for a Modular DC circuit breaker with integrated energy storage for future DC networks. This invention, known as the T-breaker, serves as an all-in-one solution for DC microgrid fault protection, power flow control, and power quality improvement. The T-breaker features a modular multilevel 'T' structure that incorporates energy storage devices. The two horizontal arms of the T-breaker are designed to manage fault current breaking, load voltage compensation, and power flow control, while the vertical arm provides shunt compensation. This configuration offers excellent voltage scalability and reduces the requirements for switching signal synchronization during fault transients. Additionally, the local energy storage in sub-modules alleviates the fault energy dissipation demands typically placed on surge arrestors. The modular multilevel structure also provides immense control flexibility for various targeted functions of the T-breaker.
