Inverter high voltage silicon replacement

What is a silicon carbide inverter?

Our solution for this challenge? The 800-Volt Silicon Carbide Inverter for Electrified Vehicles. Viper is the first 800-Volt inverter to use an innovative, double-side cooled silicon carbide (SiC)-based power switch that delivers the higher power densities and efficiencies needed to extend battery range and performance, and reduce costs.

Will SiC MOSFETs power EV inverters?

Next, on Jan. 10, 2023, Rohm Semiconductor, which began mass production of SiC MOSFETs in 2010, announced that its SiC MOSFETs and gate-driver ICs will power EV inverters developed by Hitachi Astemo, an automotive parts supplier in Japan.

Do sic semiconductor inverters reduce power loss?

A cruising test conducted under specific conditions by BEV using SiC semiconductor inverters demonstrated inverters with SiC power semiconductor reduce power loss less than half of ones with Si semiconductor. As a result, the energy efficiency of BEVs is improved and cruising range is extended.

What is a hybrid power inverter?

The hybrid power inverter proposed by STMicroelectronics integrates SiC MOSFETs and IGBTs to boost power efficiency for less. After decades of domination by silicon, silicon carbide (SiC) is replacing it as the gold standard in high-voltage power electronics, including in traction inverters at the heart of electric vehicles (EVs).

Are Si IGBT-based power switches better than SiC MOSFETs in EV inverters?

As a result, in EV inverters, Si IGBT–based power switches are increasingly being replaced by SiC MOSFETs, which deliver up to 70% reduction in switching losses, leading to improved performance and lower costs in electrified propulsion systems.

What is a silicon carbide traction inverter?

The year 2023 began with two major design wins for silicon carbide (SiC) semiconductors in traction inverters for electric vehicles (EVs). A traction inverter—located between the high-voltage battery and the electric motor in an EV—converts DC power derived from batteries to AC power used in EV motors.
