3 The Carbon Challenge Canada Source: Environment and Climate Change Canada, Canada's Emission Trends 2014 The world has used 50 % of carbon budget needed to avoid catastrophic climate change The Canadian challenge is shown Emissions must fall 50 % over the next 20 years GaN and SiC switching efficiency can play a major part in meeting the target John Roberts GaN Systems 3

4 Greenhouse Gas Emissions - Canada Automobile (Transportation) 25 % Source: Environment and Climate Change Canada (2016) Canadian Environmental Sustainability Indicators: Greenhouse Gas Emissions. Varies by Province: Alberta 11 % Ontario 43 % Quebec 45 % British Columbia 37.3 % Typical Canadian Province therefore, has circa 40 % emissions due to automotive John Roberts GaN Systems 4

5 The Automotive Imperative The Love Affair US/Canadian Automotive love affair Top priority is the uptake of electric drive, EV/HEV Massive loss reduction - 5x/10x using SiC or GaN in boost and inverter circuitry John Roberts GaN Systems 5

6 Forced Electrification! Fleet Standards Source: ICCT Policy Update, January 2014 Proposed emission standards will result in higher EV/HEV use GaN and SiC can provide a further loss 5x/10x reduction at the typical/average inverter load point compared to IGBTs There are no alternative ultra effective solutions John Roberts GaN Systems 6

7 Back to the Future First Electric Vehicle 1832! John Roberts GaN Systems 7

8 Power Switch Automobile Applications Areas Traction Inverter will use SiC or GaN Eventually other automotive applications will benefit significantly from the high speed attributes of GaN High speed GaN switches reduce the size and weight of the passive components SiC and GaN will compete for use in the Traction inverter GaN devices will own the DC-DC converter and On-board charger John Roberts GaN Systems 8

9 Projected Inverter Market EV/HEV Inverter Market (Million $US) Source: Power electronics for EV/HEV 2016: market, innovations and trends (Yole Developpement) 9 Billion $US market for SiC/GaN by 2021? IGBTs obsolete? John Roberts GaN Systems 9

11 IGBT vs. GaN Loss Simulation Traction Inverter The devices presently being used in EV/HEVs are IGBTs IGBTs are low cost well established, well understood devices Displacement will require the compelling GaN advantages to be demonstrated Given that 1 mω GaN device is available it is possible to construct the table shown Under typical operating conditions there is a tenfold reduction in power losses Source: Cherif Assad, CiPS 2012, Paper P20 25 C, 400 A Typ. values IGBT GaN Simulation V cesat : V on (V) P sat : P on (W) E off (mj) E on (mj) V F : V on (V) P VF : P Von (W) E REC : E Roff (mj) V cesat : V 100 A (V) P sat : P 100 A (W) Applying a New European Driving Cycle (NEDC) profile to these inverters have losses of 75 W h for the IGBT inverter and 5.4 W h for the GaN inverter 14x Improvement John Roberts GaN Systems 11
