Power Integrations, Inc. (NASDAQ:POWI) and Ideal Power Inc. (NASDAQ:IPWR) have agreed to collaborate on a new solid-state circuit breaker system designed for artificial intelligence data centers. The partnership combines Power Integrations' InnoMux-2 power conversion integrated circuits with Ideal Power's B-TRAN bidirectional power switches to create an intelligent circuit protection architecture for 800-volt direct current (800 VDC) systems.

As modern AI computing hardware pushes server rack power demands higher, conventional mechanical circuit breakers are proving too slow to protect sensitive electronics during electrical faults. At the same time, traditional electronic breakers create notable power loss and demand external auxiliary power. The joint solution operates directly off the 800 V power line, generating isolated power for gate drivers, sensors, and control systems while eliminating the need for separate external power supplies.

The two semiconductor companies have already built and demonstrated a functional prototype of the circuit breaker technology. They are now working together to complete a full reference design aimed at equipment makers and data center operators transitioning to high-voltage power architectures.

## Key points
