Analytical modelling of high‐frequency losses in toroidal inductors
IET Power Electronics, 2023 Toroidal inductors are widely used in power electronic systems. With the increasing switching frequency of power devices, the AC losses of high‐frequency inductor windings have become an issue that cannot be ignored in design.

Comparison of Two DC Motor Speed Observers on Sensorless Speed Control Systems
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2022 In a sensorless motor speed control system, the motor speed is not directly measured using a speed sensor, but it is estimated using an observer. The sensorless speed control systems are mostly applied to AC motors, while they have not been widely ...

Design Equations for Class-E Power Amplifiers [PDF]
, 2006 In literature, it is widely accepted that the design of Class-E Power Amplifier (PA) with finite dc feed inductance requires a long iterative solution procedure. To avoid such iterative solution methods, analytical design equations should be known.
