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.

What is a silicon based inverter?

Silicon-based inverters, primarily utilizing IGBTs and MOSFETs, have been the industry standard for decades. Their advantages include high reliability, mature manufacturing processes, and cost-effectiveness.

Why do solar inverters use silicon MOSFETs?

Silicon MOSFETs, by contrast, are primarily used in lower-power applications within solar inverters due to their fast-switching speeds and low gate drive power requirements. These characteristics enhance overall efficiency, particularly in compact, high-frequency inverter designs.

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).

Why do silicon based inverters require bulky cooling solutions?

The relatively slow switching frequency of IGBTs results in higher energy losses in applications demanding rapid switching, such as high-speed motor drives. Additionally, silicon-based inverters often require bulky cooling solutions due to higher heat dissipation, which increases system size and weight.

What is a modern inverter?

Modern inverters are designed to minimize power losses, reduce heat generation, and operate efficiently under different load conditions. They are often integrated with advanced control algorithms and passive components like capacitors and inductors to ensure stable and reliable operation.
