For those of you, who are not aware of what exactly is automotive traction inverter, this blog will provide some valuable information about the same.

The sudden increase in the number of electric vehicles is because of the increasing levels of pollution by vehicular emissions, and the initiatives of various governments to encourage the purchase of EVs, as opposed to their conventional counterparts.

Drivers of HEV and all the other variants rely on automotive manufacturers to provide a safe, dependable and relaxed driving experience. The automotive traction inverter, an important component in the electrified drive-train, directly influencing the driving experience, the range of batteries and the overall vehicle safety. 

The main purpose of the traction inverter is converting the DC current from the battery of the electric vehicles to AC current, which is to be used in the electric motor for driving the propulsion system of a vehicle. It has an important role to play in in capturing energy from regenerative braking and transporting it back to the electric vehicle battery.

High Level of Integration and Power Density

•    There are two kinds of automotive traction inverter. The first is separate packaged, these are the inverters, which are commonly used by more than a few system suppliers and automotive manufacturers. 

These inverters have both ease of assembly with a modular design method and has frame-based, silicone-gel-filled power modules in 6-pack or tailored formations, from time to time even including charger or booster topologies.

•    The second is an integrated inverter design, where there are small and completely encapsulated apparatuses are located within the mechanical compartment of the drive-train. 

Here, even PMSM are frequently intended as part of the transmission system incorporating the power inverter into that very housing.

The requirement for higher integration levels is increasing. The electrical machine concept as well as all the power electronics desirable for a frequency inverter, corresponding needs for cooling, vibration and sturdiness, is fairly attractive when it comes to weight or volume restrictions and overall cost of the system.

Making the Most of Automotive Traction Inverter

Most of the automotive traction inverters have a multichip-semiconductor power module. It can include of diodes or MOSFET dies, IGBTs, and the characteristic circuit topologies are six-pack.

The continuing trend toward mechatronic incorporation of power electronic components and mechanical assemblies needing more mechanically robust and compact power modules.  The power modules design act as an essential element in attaining advanced power density levels and gratifying more and more strict requirements. 

Molded packaging tech is a solution, but compact designs and integration challenges the component’s thermal management. So, there is a need for a high-performance but cost-competitive, and compact liquid-cooling system.

It is because of the increased demand of electric vehicles, the requirement for automotive traction inverters is growing, and will continue to do so in the years to come.
