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 ...

The U.S. Department of Energy has indicated that 65 percent of electrical energy used in commercial and industrial systems comes from electrical motors powering centrifugal pumps and fans. Also, the ...

You can divide the world of electronic motor drives, which control the speed, torque, direction, and resulting horsepower of a motor, into two categories: ac and dc. An ac drive controls ac induction ...

This file type includes high resolution graphics and schematics when applicable. Electric drives consume a tremendous amount of energy in most manufacturing facilities. Virtually every automated ...

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 ...

Alex Lidow and Marco Palma look at the value of high-frequency motor drives, their advantages and the capabilities of GaN technology, which make them suitable for today’s demanding applications.

A motor control IC is a convenient way to implement custom motor drive algorithms such as the single-phase induction motor (SPIM) control. A generalized control algorithm, implemented and tested in an ...

Nord Drivesystems has been developing drive electronics for more than 30 years and is one of the pioneers of innovative inverter technology. With their family of NORDAC variable frequency drives (VFDs ...

High-frequency link matrix converters and inverters represent a transformative development in power electronics, combining direct AC–AC conversion with high-frequency pulse width modulation (PWM) to ...

EPC has come up with a 3-phase BLDC motor drive inverter reference design which operates from an input supply voltage range of 14 V to 60 V and delivers up to 60A output current. This voltage range ...

Adjustable speed drives (ASDs) or variable speed drives (VSDs), also called variable frequency drives (VFDs), typically control a motor's velocity or torque output. Most adjustable frequency drives ...
