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 ...

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 ...

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 ...

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 ...

For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...

Pulse-width modulation (PWM) is an efficient method for controlling the light intensity of a lamp or the speed of a simple DC motor. It lets you take advantage of the load's inertia by switching the ...
