Annual Meeting Atom Power, Inc. Mass Market SiC Solid-State Circuit Breaker Development January 17-19-2017 December 8 2015 1 ¡
Atom Power’s role in WBG Technology • First commercially viable solid- state circuit breaker for mass market production • Utilizing SiC for short circuit and overcurrent protection in 3-phase AC and 2-pole DC power distribution • Fastest circuit breaker in the world (as far as we know) due to our own overcurrent detection and SiC switching speed The Atom Switch TM 2 ¡ (2-pole DC version shown)
Project Objectives The goal of Atom Power for this project is to build upon our existing knowledge base and develop higher ampacity SiC solid-state circuit breakers to penetrate the full commercial and industrial building markets. Atom Power BP2 project: • 800-amp Atom Switch using SiC circuit breaking • 480VAC • 3-phase • 4,800-amp instantaneous ride- through • 200,000-amp interrupting capacity • UL 489 ready 3 ¡
Accomplishments and Outcomes 2015 2016 (1 st half) 2016 (2 nd half) 2017 ALPHA BETA Release Candidate AC/DC UL Testing scheduled Atom Switch for 100-amp versions AC Atom Switch AC Atom Switch March, 2017 - UL dry-run Integrated Motor Soft- - 100,000A rating was Starting achieved 800-amp Atom Switch - UL firmware approval release (BP2 Project) 4 ¡
Accomplishments and Outcomes Barriers to further maturity • SiC products at 1200V blocking with low R DS are still prohibitively expensive for mass market applications in circuit protection ( see next slide ) • Need to address limitations to packaging resources – Takes a long time to make – Few options (for our configurations) – Few resources available 5 ¡
Pathway to Market • In the short term, there is a significant premium to pay for a solid-state circuit breaker. • Therefore, the focus initially is on motor controls: • Motor circuit protection • Arc flash protection • Integrated motor soft-starting • Integrated ANSI relay protections • Remote control • Built-in metering This is effectively a • Communication aggregation Motor Control Center at 20% of the size and about 75% of the cost with ~2X the value Atom OS TM Atom Panel TM (UI) 6 ¡
Broader Impact on the WBG Community • Atom Power is bringing WBG devices to mass market. $30B per year serviceable market in US • Atom Power has taken an uncommon approach to the use of SiC devices by implementing them as short circuit and overload protection and is therefore opening up an entirely new industry for the WBG community Future Direction • Atom Power will be developing devices for up to 4,000- amp circuit breaker applications • Artificial intelligence development for self-coordination of solid-state circuit breakers 7 ¡
