A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Q. What is the Code rule for sizing short circuit and ground fault protection for a motor feeder? A. Feeder conductors must be protected against short circuits and ground faults by a protective device ...

Have you ever wondered why a car’s city fuel economy is always lower than its highway fuel economy? Most cars spend a lot of time stopping or traveling at low speeds, especially in a city. Start-stop ...

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...

Often, many different types of protection of the power transistor, motor or any part of the system are required in motor drive applications. Current protection of the inverter is one of the crucial ...

Using a gate drive optocoupler with MOSFET buffer driving capability enables users to scale IGBT gate drive designs to the power requirements for a wide range of motor drive and inverter systems.
