Automotive Inverter | Setting a New Trend in Electric Vehicle Segment
Automobile components manufacturers are making various breakthroughs, especially, in the battery and the automotive inverter technologies, to introduce a whole new range of alternative energy vehicles.
Since the automotive inverter is such a crucial component of alternative energy vehicles, demand from, both, original equipment manufacturers (OEMs) and aftermarket vehicle components suppliers are projected to increase in the future, generating substantial changes in the mobility sector.
Also, when these technologies and materials reach their optimal levels of development, prices for alternative energy vehicles are expected to reduce.
The global automotive inverter market is rapidly growing as a result of various innovations and technological advancements in the automotive industry, paving the way for alternative energy vehicles such as battery electric vehicles (BEVs), and hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs).
The global automotive inverter market was estimated to be at $8.3 billion in 2020, which is expected to grow at a CAGR of 17.09% and reach $50.1 billion by 2031.

What are the Key Trends Shaping the Automotive Inverter Industry?
Let’s understand the following variables affecting the automotive inverter sector:
• Double-Sided Direct Cooling Inverters: These inverters can reduce the cost and weight of a common inverter by providing thermal insulation to the inverter system. Dual-sided cooling is the best and most economical path toward lower-cost and more compact hybrid electric vehicle (HEV) and electric vehicle (EV) inverters.
This module may make use of both sides of the inverter, which helps to reduce thermal resistance and contributes to improved power dissipation and current flow in the inverter.
The performance of double-sided direct cooling inverters is enhanced at the expense of increased pressure loss in the cooling water channels. The best position can be chosen based on the cooling capacity since it increases the resistance to water flow in the channels.
• Multilevel Inverters: The primary function of the multilevel inverter is to synthesize the required voltage from multiple layers of direct current (DC) voltages.
The multilevel voltage enables inverters to achieve high voltages and power levels without the use of transformers. They’re perfect for high-voltage vehicle motors that require low total harmonic distortion (THD) and electromagnetic interference (EMI).
Large EV or HEV drives demand a lot of power, which multilevel inverters can easily provide.
As the number of levels increases, the synthesized output waveform includes more steps, resulting in a staircase wave that approaches the ideal waveform. The synthesized output waveform has more steps than the required waveform, resulting in a staircase wave.
In addition, as the number of levels in the waveform grows, the harmonic distortion of the output wave decreases, eventually nearing zero.
The voltage that connecting devices (circuit breakers, disconnectors, isolators, and many more) can cover in series grows as the number of levels increases. The active devices have no voltage sharing difficulties because of the structure of the multilayer inverter.
Multilevel inverters are frequently used because of their high output power and high voltage level applications. Inverters with multiple levels of operation are known as multilevel inverters.
• Integration of Inverter and Direct Current (DC) Converter: Inverters and converters operate together to handle a vehicle’s electric powertrain and auxiliary systems.
The demands of these complex systems could be fulfilled by integrating a high voltage inverter and a DC/DC converter.
This integration eliminates the need for additional DC-insulated-gate bipolar transistor (IGBT), liquid cooling lines, and housing, resulting in improved efficiency with reduced space and weight occupancy in vehicles and improved cost and packaging.
The new system (integration of inverter and DC converter) enhances longevity and dependability with features engineered to endure temperature extremes under the hood and in the environment.
It also improves voltage distribution functionality, allowing both low- and high-side power to be used for everything from headlights to power steering and air conditioning by eliminating cabling, cooling hoses, connections, and housings.
To summarize, the global automotive inverter market is rapidly expanding as a result of many breakthroughs in the electric vehicle sector, opening the way for alternative energy vehicles.
