How GaN ICs are Transforming the EV Market
As the global energy mix transforms to adopt low-carbon energy sources and energy-efficient transportation, pressure mounts for energy efficient cars. Today, the overall Electric Vehicle (EV) market already outpaces the conventional Internal Combustion Engine (ICE) vehicle market growth rate by 10x. The EV market is estimated to own 35% share of new vehicle sales by 2040, a remarkable portion of new automotive sales for a market that started mass production less than 10 years ago. Economics combined with innovations in battery, electronic systems, and system components have played a crucial role in EV growth as the overall automotive industry moves from mechanical-based systems to digital ones. This paper will examine how galium nitride (GaN) electronics, and to a lesser extent silicon carbide (SiC), are boosting the power output and energy efficiency of electric cars without increasing the cost of the vehicles.
