Flying Capacitor Multilevel Inverter Reduces Harmonic Loss in High-Speed Motor Drive Systems
When inverters drive an AC motor, the harmonic components of the output voltage caused additional iron and copper losses in the magnetic cores of the motor. Since inductance is supposed …
With the increasing use of renewable energy sources, the need for reliable and efficient grid-side inverter fault detection and protection is becoming more important. Because the magnitude of fault current …

PV-Wind-Battery-Based Grid-Connected Bidirectional DC-DC Coupled Multi-Input Transformer
This study provides a hybrid approach to PV/wind/battery system control. A transformer-coupled bidirectional DC-DC converter is used to control the power flow. The proposed system is designed to meet the …
Wind power, another attractive and well-developed renewable energy source, has recently emerged. A power electronic interface is required to connect a wind energy conversion system (WECS) to the load or …
Since an induction motor (IM) is commonly used as a drive in industry, it must be protected against common faults such as overvoltage, overcurrent, overload, overtemperature, and undervoltage. Timers, contactors, …

Voltage Level and Stability Estimation, Control, and Prediction at the Receiving Node
This article is about the voltage stability of receivers. Voltage stability and level are concepts that are inseparable. Although this is a good indicator that you are close to the …
There is an urgent need for a mechanism for precisely identifying the battery’s state of charge (SOC), as LiFePO4 (LFB) batteries are being used in more portable devices. In this …
The research presented here reports enhanced-boost quasi-Z-source inverters (qZSI) using two switching impedance networks (continuous input current configuration and discontinuous input current configuration). These suggested inverter designs, which are comparable …
These findings show how an integrated UPQC-P array performs dynamically for critical loads, such as solar photovoltaic arrays (SPV-UPQC-P). The SPV-UPQC-shunt P’s compensator, connected across the load, transfers electricity from …
