Crystal high power inverter

How a high power density inverter is developed?

We also developed gate driver to reduce switching losses and switching delay time. The prototype high power density inverter is developed with the developed power module and the proposed gate driver. The volume of the prototype inverter is about 0.5 liter and the weight is about 660g.

What is the power density of SiC-based high power density inverter?

Abstract: This paper introduces the development and experimental performance of SiC-Based high power density inverter. The Power density of the developed inverter is about 70kW/litter in volumetric, 50kW/kg in gravimetric. The inverter is forced air cooled 2-level voltage source inverter.

What is the power density of an inverter?

The Power density of the developed inverter is about 70kW/litter in volumetric, 50kW/kg in gravimetric. The inverter is forced air cooled 2-level voltage source inverter. In order to achieve higher power density than conventional inverters, we need to reduce losses of inverters or improve cooling systems of inverters.

Which EV traction inverter is best?

For EV traction inverter, more efficiency and right performance are key. While IGBT is ideal for cost-optimized drive-train, SiC demonstrates higher efficiency under WLTP partial load scenario. Infineon offers the best scalability in market between IGBT and SiC, allowing customers to freely choose the technology for their needs,

How much power does a prototype inverter have?

The volume of the prototype inverter is about 0.5 liter and the weight is about 660g. Experimental results confirmed that the prototype inverter is able to operate up to 35kW, which means the power density of the prototype inverter is about 70kW/liter and 50kW/kg. The efficiency of the prototype inverter is more than 98%.

Are Infineon IGBTs compatible with empower inverters?

market. Infineon’s industry-leading discrete IGBTs are compatible with Empower‘s latest generation inverter in terms of packaging. Together with the high current density, ultra-low saturation voltage drop and superior parallel performance, Discrete products has increased power density by more than 20%.
