BEV - By Propulsion

BEVs are leading the traction inverter market due to the global transition towards zero-emission mobility and government incentives driving electrification. With purely electric power at their disposal, BEVs require high-efficiency traction inverters to convert the battery's DC power into AC for the electric motor.

More specifically, due to the duties performed by these inverters, vehicle range, performance, and power efficiency is greatly improved. BEV segment mainly operates under 200V and lower voltage range strongly favors IGBT based Inverter on account of overall low-cost solution and high-power capacity.

But now, third generation SiC, driven by BEVs with higher operating voltages (up to 800V), continue to require BEVs, which include faster charging and improved efficiency. Major automotive players like Tesla, Volkswagen, and BYD are pouring money into next-generation inverters to improve power density and thermal management.

With BEVs and PHEVs leading as traction inverters for EVs, greater EV climbing rates in China, Europe and North America will only see BEV-set traction inverters are up for a strong forecast of the next years.

IGBT- By Technology

The Insulated Gate Bipolar Transistor (IGBT), which is a semiconductor technology powering various types of traction inverters, also carries variations and is a common element across many battery electric vehicles (BEVs) and during vehicle types such as hybrid electric and plug-in hybrid electric vehicles (HEVs and PHEVs).

When compared to other high-voltage devices like bipolar transistors, IGBTs have higher efficiency because they combine the advantageous properties of both MOSFETS and bipolar transistors. Thus they play a very important role in converting the constant current battery power to alternate current that runs the electric motor, so that electricity can flow without wastage.

IGBT based inverters are suitable for low and mid voltage EV (up to 900V) as they provide high power density and cost effective and sturdiest thermal performance. Because of its tried-and-tested reliability and worth, IGBT is still the most used in the mass-market EV segments, particularly passenger autos and commercial electric.

Commercial - By Vehicle

Commercial vehicle electrification continues to gain momentum, driven by the global shift towards zero-emissions vehicles and the need for fleet operators to save on fuel costs. Commercial applications with electric buses, trucks, and delivery vans require high-power traction inverters for processing higher voltage levels (>900V) and heavy-duty performance requirements.

Commercial EVs require tougher, more capable inverters than passenger EVs due to longer operating hours, higher torque ratings, and frequent load changes. Leading manufacturers Daimler, Volvo, Tesla and BYD are also investing in next generation traction inverters using silicon carbide (SiC) technology to improve efficiency, reduce thermal losses and increase driving range.

The growing popularity of electric commercial fleets most notably for urban logistics, public transpiration, and freight applications is generating demand for high-voltage, hard-wearing inverters. The commercial vehicle segment is likely to observe substantial growth in the traction inverter market over the next 10 years owing to strict emissions norms and the implementation of government rebates for electric trucks and electric buses.
