Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

All DC/DC converters have an output ripple voltage due to the charging and discharging of the output capacitor with each pulse of energy from the internal oscillator. This output ripple has a ...

Download this article in PDF format. Arbitrary function generators (AFGs) are used to generate many different types of electrical waveforms, such as sine waves, square waves, triangular waves, and ...

This article presents another type of regulator switching topology, which are the isolated DC/DC converters. It covers the flyback and forward DC/DC converter, active clamp forward converter, ...
