Abstract: Brushless dc (BLDC) motor drives have gained significant attention due to their merits such as high efficiency, high dynamic response, high reliability etc. From the literatures, it is ...

The simple circuit was designed using a 555 timer and pulse width modulation for controlling the speed of DC motor. The pulse width modulation (PWM) pertains to the process of switching the power ...

Pulse Width Modulation (PWM) is a fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...

Abstract: In motor drive system fed by voltage source inverter (VSI), common-mode voltage (CMV) is commonly present because of pulse width modulation (PWM) techniques. It's proved to be feasible in ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

The DPW Series pulse-width-modulated dc motor-speed control designed in a compact SMT package. The DPW Series pulse-width-modulated dc motor-speed control designed in a compact SMT package. The ...

Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

Why PWM? Switch-mode converters employ a power semiconductor switch (usually a MOSFET) to drive a magnetic element (transformer or inductor) whose rectified output produces a dc voltage. Efficiencies ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...

Mouser Electronics is now stocking the VIPer01 high-voltage converters from STMicroelectronics (ST). Part of the VIPerPlus family of high-voltage converters based on ST’s Bipolar-CMOS-DMOS (BCD) ...
