Annual Meeting Atom Power, Inc. Mass Market SiC Solid-State Circuit Breaker Development

January 17-19-2017

Atom Power’s role in WBG Technology

2 ¡

• First commercially viable solid-

state circuit breaker for mass market production

• Utilizing SiC for short circuit and
• vercurrent protection in 3-phase

AC and 2-pole DC power distribution

• Fastest circuit breaker in the

world (as far as we know) due to

• ur own overcurrent detection

and SiC switching speed

The Atom SwitchTM (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

BETA AC Atom Switch

2016 (1st half)

Release Candidate AC/DC Atom Switch

• UL dry-run
• 100,000A rating was

achieved

• UL firmware approval

2016 (2nd half)

UL Testing scheduled for 100-amp versions March, 2017 Integrated Motor Soft- Starting 800-amp Atom Switch release (BP2 Project)

2017

Accomplishments and Outcomes

Accomplishments and Outcomes

Barriers to further maturity

• SiC products at 1200V blocking with low RDS 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

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:

Atom PanelTM Atom OSTM (UI)

This is effectively a Motor Control Center at 20% of the size and about 75% of the cost with ~2X the value

• Motor circuit protection
• Arc flash protection
• Integrated motor soft-starting
• Integrated ANSI relay protections
• Remote control
• Built-in metering
• Communication aggregation

7 ¡

• 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

Broader Impact on the WBG Community
