Thermal impedance spectroscopy is used to obtain the thermal parameters of a battery cell. Here, by utilising the cell temperature, the influence of thermal gradients on the resulting measurement is minimised, avoiding negative real values at all frequency points. The paper, therefore, compares multiple cell states and formats to gain insights into the

Mitigation of Motor Overvoltage in SiC-Device-Based Drives using a Soft-Switching Inverter
In SiC motor drives, the high-voltage slew rate (dv/dt) of switching transients results in excessive motor overvoltage, due to the reflected wave phenomenon (RWP), which stands behind the premature failure of motor winding insulation while raises ...

Due to complex wind farm conditions, a coordinated control system was designed. It manages DC power surges during AC faults by temporarily storing excess energy and regulating voltages. This strategy optimizes unbalanced power and enables effective fault recovery, resulting in minimal voltage fluctuations and superior performance.

A Control Strategy for Variable Speed Condenser Based on Doubly‐Fed Machine
This paper proposes a variable speed condenser (VSC) control strategy based on a doubly fed machine. It can be installed in PV stations and wind farms to enhance the grid‐connection performance of renewable energy power plants. ABSTRACT The lack of active power support capability in power systems with large‐scale renewable energy integration has become

A fluorinated cyclic ether, FDOL, is shown to stabilize Mg metal anodes by tuning Mg2+ solvation of the G2 electrolyte. The G2‐FDOL electrolyte suppresses passivation and thick, diffusion‐blocking Mg deposits, enabling more uniform Mg plating/stripping and sustained interfacial reactions.

Switchable Photoelectrochemistry in Thin Films of SbSI Microrods
Thin film electrodes consisting of SbSI microrods demonstrate photoelectrochemical properties that can be tuned by adjusting the film thickness, pH of electrolyte, and O2 concentration. The performance of SbSI electrodes can also be switched by changing the temperature and thus employing the ferroelectric transition.
