Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

Included among the many applications for pulse-width modulation (PWM) are voltage regulation, power-level control, and fan-speed control. A PWM circuit for such systems can be implemented with three ...

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 ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

A friend bought an electric jacket to wear on his motorcycle. But it was on all the time when it was plugged in, which made him sweaty at certain temperature ranges. He was looking for a way to ...

The DS1050 is a single 5-bit, programmable pulse-width modulator with an adjustable duty cycle from 0% up to 100%. It features a 2-wire serial port interface that supports a bi-directional data ...

An interferometer modulator uses a beamsplitter to produce deflected and transmitted light beams onto mirrored surfaces of a piezoelectric crystal pair, one piezoelectric crystal being driven by a ...
