Inverters used to control a motor’s speed or torque — also known as variable frequency drives (VFDs) or adjustable speed drives — can induce unwanted motor shaft voltages that cause premature motor ...

Motor drives and Inverters work in high voltage domains and require safety isolation and protection to meet regulatory requirements. Optocouplers have been the defactor standard in providing this ...

All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings ...

Tesla manufactures its drive inverter for the Model S/X in-house at its Fremont factory, but the automaker is using proven off-the-shelf products — primarily TO-247 transistor packages. The company ...

Auto manufacturing expert Sandy Munro knows cars the way a surgeon knows bodies. His company performs teardowns, taking new cars apart and analyzing every little bracket and screw to find out what ...

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today it has developed a prototype electric vehicle (EV) motor system with a built-in silicon carbide inverter. The EV ...

Munro and Associates have continued their teardown of the Tesla Model S Plaid they acquired with this goal. This time, the motors and their inverters were in line to be opened and analyzed, and ...

Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

A Z-source Inverter (ZSI) is a DC-to-AC converter that can perform both buck and boost functions as a single stage. A unique attempt of ZSI is the shoot through state, by which two switches of the ...
