Ideal Power Inc. announced the launch of its first commercial product, the SymCool™ Power Module. This multi-die B-TRAN™ module, rated at 1200V 100A and incorporating double-sided cooling, is designed to meet the very low conduction loss needs of the solid-state circuit breaker (SSCB) market. Modules can be paralleled to achieve a wide range of high power SSCB ratings for utility, industrial and military applications.

Key advantages of the SymCool™ Power Module include: Energy Savings: Circuit breakers continuously conduct current, so it is critical to keep conduction losses to a minimum. The SymCool™ Power Module exhibits dramatically lower conduction losses compared to IGBTs, thereby allowing for energy savings that are necessary as power grids are modernized. In particular, integration of renewable energy sources and energy storage systems into the grid will require circuit breakers that do not waste the precious energy generated by solar or wind.

The low conduction losses of the SymCool™ Power Module meet this requirement. Bidirectional: Fewer Switches Needed: The SymCool™ Power Module utilizes Ideal Power's groundbreaking innovation of a dual-sided semiconductor with inherent bidirectional capability. Existing power semiconductors, such as IGBTs, are single-sided and operate as unidirectional switches.

The SymCool™ Power Module takes the bidirectional concept, validated in the Ideal Power B-TRAN™ single-chip package, to a higher-current capability using multiple B-TRAN™ chips configured in parallel. The result is a product that will finally enable the SSCB market. In addition to saving energy, the inherent bidirectional capability of the SymCool™ Power Module means that half as many high-voltage switches are needed compared to implementation with IGBT modules, which need a dedicated switch for each direction of energy flow.

Fewer components translate to a smaller, more cost efficient SSCB. As new applications, such as Vehicle-to-Grid, Vehicle-to-Home, and Vehicle-to-Vehicle (V2X) emerge with the adoption of electric vehicles, bidirectional functionality is needed. Renewable energy microgrids and key military applications also require bidirectional circuit breakers that operate quickly, and the bidirectional SymCool™ Power Module offers clear advantages for SSCBs in these applications.

Advanced Packaging: Another benefit realized by the dual-sided structure of B-TRAN™ is the advanced module packaging developed to maximize thermal efficiency. The SymCool™ Power Module has innovative dual-sided cooling with built-in temperature sensing. Heat is dissipated from both the top and bottom surface without wire bonding to meet the ever-increasing demand for reliability, durability and efficiency.

This allows for a smaller, lower cost thermal management system, and greater overall efficiency of the SSCB. The SymCool™ Power Module offers a compelling solution to SSCB applications with its combination of greater efficiency, bidirectional capability, and advanced dual-sided cooling package. This will enable a new generation of very fast acting SSCB designs, while simultaneously saving energy, allowing more compact equipment, and saving overall system cost.

Circuit Breakers are Everywhere: Circuit breakers perform critical functions in controlling the flow of electricity and containing high currents created by faults in that flow in a wide variety of applications. In addition to high demand for circuit breakers from renewable energy, microgrids, energy storage, and EV applications, there is tremendous need to upgrade aging infrastructure, including utility transmission and distribution networks and railway systems. Two critical circuit breaker operating requirements are fast switching and low conduction losses.

Traditional mechanical circuit breakers are slow acting and prone to wear and arcing; IGBT and MOSFET-based SSCBs suffer from high conduction losses. The fast-switching speed of B-TRAN™ solves the slow operating time and electrical arcing of electromechanical circuit breakers while also providing more than 50% lower conduction losses compared to SSCBs utilizing conventional semiconductor power switches. These result in lower cost and less complex cooling systems, benefits that significantly impact the economics of SSCBs and improve the economics of transmission and distribution.

This is why B-TRAN™ is an enabling technology for SSCBs.
