Average Current Reconstruction Method for Ultra-Low Inductance PMSM Using a Single DC-Link Current Sensor

IEEE Access
This article proposes a method to minimize current reconstruction errors when driving ultra-low inductance permanent magnet synchronous motors (PMSMs) using a single current sensor system for three-phase voltage source inverters.

Reduced‐order electromagnetic transient model based on equivalent flux linkage derivative for induction motors under voltage sag condition

IET Electric Power Applications
Precise electromagnetic transient simulation of induction motors (IMs) under voltage sag condition is necessary in Electro‐Magnetic Transient Programme. Although traditional fifth‐order model can accurately reflect the electromagnetic transient behaviour

Optimal Compensation of Voltage Drop Across Long Power Cable in Motor Drive Systems: A Vector Controlled Approach

IET Electric Power Applications
This paper proposes an optimal voltage compensation method for the drop across long power cable in a motor drive system. In the proposed method the drive is utilised to compensate the voltage drop and no additional voltage regulation device is required ...

Induction Motor Under Unbalanced Voltage Subharmonics

IEEE Access
In addition to fundamental harmonics, the voltage waveform may contain various undesirable components, including subharmonics (subsynchronous interharmonics) and interharmonics (SaIs), which are components with frequencies less than or not an integer ...
