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 ...

Inverter technology is the unsung hero of the HVAC world. Initially used primarily in high-end and ductless HVAC equipment, it is now being incorporated into a wider range of systems. Air-source heat ...

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.

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 ...

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 ...
