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 ...
What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...
Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...
For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...
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 ...
Simply adding a diode and potentiometer to a 555 timer operating in the asynchronous mode yields a pulsewidth modulator (PWM) with a duty factor adjustable from 1% to 99% (Fig. 1). Applications would ...
BHPian BlackBeard recently shared this with other enthusiasts:Hello folks. Since many enthusiasts here are keen on knowing ...
Using pulse outputs from a PLC is a cost-effective way to get simple motion. Most, if not all, PLC manufacturers provide a way to control servos and steppers using a pulse train signal. So when a ...
The DC motor is widely used in the field of servo automation and robotics. The operating principle of an electric motor is based on the interaction of two magnetic fields that attract and repel each ...
Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...
With the appropriate driver IC and microcontroller, designers can exploit the brushless motor's declining price, smaller size, lighter weight, and minimal maintenance. As recently as two years ago, ...
