Q&A with EV measurement engineering experts Coty Harrison and Cristian Loris of Yokogawa Test&Measurement. When tasked with measuring the electrical power of complex systems like EVs, an inexperienced engineer may first reach for general instrumentation like oscilloscopes, data acquisition (DAQ) systems and digital multimeters (DMMs). While these instruments serve useful roles in electrical testing—oscilloscopes analyze… Read more »

A closer look at multilevel traction inverters
The vast majority of EV traction motors must be supplied with sinusoidal 3-phase alternating current with the frequency proportional to RPM, and the overwhelmingly favorite way to do this is with a triple half-bridge voltage source inverter, or VSI. In this topology, each bridge switch can connect its output terminal (i.e. motor phase winding) either… Read more »
CGD unveils 100 kW+ GaN technology for EV inverters
UK-based semiconductor company Cambridge GaN Devices (CGD) has developed gallium nitride (GaN) technology that combines its ICeGaN HEMT integrated circuits (ICs) and Insulated-Gate Bipolar Transistors (IGBTs) in the same module for EV powertrain applications over 100 kW. The Combo ICeGaN approach takes advangage of the fact that ICeGaN and IGBT devices can be operated in… Read more »
