Efficient Power Conversion (EPC), a developer of enhancement-mode gallium nitride (eGaN) power devices, has announced the ...

Three-phase four-switch inverters represent a cost‐effective and efficient alternative to conventional inverter topologies, offering reduced component counts while maintaining robust performance.

This solid-state thyristor (SCR) switch circuit is perhaps the simplest means of reversing a 3 phase motor. “Static” is a catch-all term that essentially means without moving (mechanical) contacts ...

There are several reasons to use a three-phase inverter to run a single-phase induction motor, including isolation from variable power grids, reduction of peak currents and elimination of the starting ...

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...
