Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Combining a control, a 24V-dc brushless motor, a gearhead, and an optical encoder allows the digital-PWM (pulse-width-modulation)-controlled version of the vendor’s Integramotor to reduce wiring ...

El Segundo, Calif.—International Rectifier introduced the IR3651, a synchronous PWM control IC designed for high-performance synchronous DC/DC buck applications with an input voltage range up to 75-V.

Since the early 1990s, the power requirements for VCC core voltages for leading-edge processors and ASICs have become increasingly demanding, with chip voltage decreasing and current increasing. Early ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

A Dutch-designed pulse-width modulation (PWM) system for sprayers claims greater flexibility and application quality compared with other options on the market. On traditional crop sprayers, the only ...
