This is yet another project born of necessity. It’s a simple circuit, but does exactly what it’s designed to do – dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate ...

San Diego, Calif.—ROHM Electronics has introduced an H-bridge driver IC line, offering designers a simple upgrade path to pulse-width modulation (PWM) speed control using either analog or digital ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

Pulse-width modulated motor drives are becoming the dominant method of variable speed motor control, and are being used not only in industry, but in applications as diverse as electric vehicles and ...

To manage and regulate power with both efficiency and finesse, electronics designers turn to Pulse Width Modulation (PWM).

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude Pulse width modulation is a form of signal ...

Texas Instruments has optimised a pair of DSPs for field-oriented motor control in domestic appliances such as washing machines, vacuum cleaners and lawn mowers.

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...
