To control system operation, motors require a current measurement, which can be achieved using shunt resistors that provide a simple and cost-effective solution. Motors are used in countless consumer ...

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 ...

Inverters used to control a motor’s speed or torque — also known as variable frequency drives (VFDs) or adjustable speed drives — can induce unwanted motor shaft voltages that cause premature motor ...

Hybrid electric vehicles (HEVs) save fuel because of their electric motor drive. In an HEV, the propulsion system can be configured several ways, for example in the electric motor assisted mode or in ...

Soft-switching inverters represent a significant advancement in power electronics, enabling reduced switching losses and enhanced overall efficiency. These devices utilise techniques such as ...

All major manufacturers of three-phase ac induction motors offer “inverter-duty” or “inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings ...

The converters normally employed with solar and wind power generation systems must work reliably under a wide variety of operating conditions. It is customary to protect the IGBTs 9 insulated gate ...

Researchers in Iraq have designed a multi-level cascaded inverter that can purportedly produce high-quality sinusoidal output voltage and current waveforms, while reduing harmonic distortion. It uses ...
