A closer look at multilevel traction inverters
- Most EV traction motors require sinusoidal 3-phase AC with frequency proportional to RPM, typically supplied by triple half-bridge VSIs.
- Traditional 2-level inverters produce square waveforms with high harmonic content that can lead to heating, torque reduction, and vibration.
- Increasing PWM frequency to reduce harmonic content leads to higher switching losses, requiring faster switches like SiC MOSFETs and GaN HEMTs.
- High-speed switching in inverters causes RF noise and common-mode currents, necessitating the use of dV/dt filters to mitigate these issues.
- Multilevel inverters (MLIs) offer lower THD and common-mode currents by generating output voltage levels with additional steps.
- MLIs require separate voltage sources for each level or use capacitive voltage dividers to create voltage levels indirectly.
- Neutral Point Clamped and Flying Capacitor are 3-level MLI types that offer different methods of generating the 0 V output level.
- Active Neutral Point Clamped and T-type MLIs balance charge on divider capacitors and handle loads with a wide power factor range.
- MLIs present challenges in terms of complexity, component count, and development costs compared to 2-level VSIs.
- While MLIs offer advantages, such as reduced noise and common-mode currents, the argument for their adoption in EVs is challenging.
- Consideration of filter addition to existing inverters may be a more straightforward solution for reducing noise in EV applications.

Electric buses are taking over Canada’s cities—but hydrogen refuses to die
- Transit agencies in Canada are increasingly adopting electric buses for their fleets.
- The Toronto Transit Commission (TTC) has ordered a total of 340 battery-electric buses, with deliveries expected to be completed by 2026.
- Other Canadian cities, such as Ottawa, Montreal, and Saskatoon, have also planned to transition to a fully electric fleet in the coming years.
- While some cities have experimented with hydrogen fuel cell buses, the focus remains primarily on battery-electric buses due to cost and operational considerations.

What Tesla can and can’t do in California with its new passenger transportation permit
- Tesla has been granted a transportation charter permit (TCP) by the California Public Utilities Commission, allowing the company to operate a private transportation service.
- This permit is different from the permits held by Uber and Lyft and only enables Tesla to offer prearranged transportation services using its own vehicles and employees as drivers.
- The permit does not cover autonomous vehicle testing or deployment, and Tesla needs additional permits from the California Department of Motor Vehicles for such operations.
- Tesla plans to initially use the TCP permit for transporting its employees and will notify the CPUC when it transitions to transporting the public.
