Rotor position sensing has long relied on resolvers because of their reliable performance in demanding automotive environments. Resolvers are still reliable, but the technology landscape has changed, and equally dependable alternatives can now do the … [Read more...]
Part I: Rotor position sensing challenges in EV traction inverters
Rotor position sensing plays a critical role in electric vehicle (EV) traction inverters by providing the angle feedback needed for precise motor control. As inverter systems move toward higher efficiency and power density, enabled by higher … [Read more...]
Bosch starts US sample production of 200-mm silicon carbide chips
Bosch has signed an agreement with the US Department of Commerce for up to $225 million in direct funding through the CHIPS Program Office. The funding will support the company’s investment of up to $2 billion to convert its Roseville, California, … [Read more...]
Why integrated EDUs are reshaping electrified drivetrain development
Electrified drivetrain development is increasingly constrained by higher voltage architectures, tighter packaging envelopes, and rising efficiency expectations. At the same time, validation cycles for motors, inverters, and gearsets are becoming … [Read more...]
How higher-voltage EV architectures are impacting battery and power-system testing
Electric vehicle (EV) architectures are advancing toward the 800-V class and beyond, which is reshaping how engineers test batteries, inverters, converters, and high-performance compute subsystems. These systems now require power platforms … [Read more...]
What AI tools are available for EV design and validation?
Artificial intelligence (AI)-driven chatbots, tools, and techniques are being deployed across various stages of electric vehicle (EV) design and simulation to support validation and manufacturing. AI can be used as an assistant to increase the … [Read more...]
How voltage impacts EV efficiency, performance, and cost
As electric vehicle (EV) platforms evolve toward longer ranges, faster charging, and higher performance, the voltage strategy has become a defining factor in powertrain architecture. Inverter systems are no longer just electrical components; they're … [Read more...]
What is driving development of EV inverters?
EV inverters, also known as traction inverters, convert the dc electricity from the battery into the three-phase variable frequency ac that's needed to drive the motor at a given speed (Figure 1). EVs use asynchronous (induction) motors or sometimes … [Read more...]
