Pulse-width modulation is a simple way to modulate, or change, a square wave. In its basic form, the duty cycle of the square wave changes according to some input. The duty cycle is the ratio of high ...

IRVINE, Calif.--(BUSINESS WIRE)--Toshiba America Electronic Components, Inc. (“Toshiba”) has launched the “TB67B000AHG,” a new three-phase brushless motor driver for home appliances such as ...

…which would take a pulse-width-modulated waveform at any frequency, and produce a signal with exactly the same mark/space ratio, but at a nominated frequency (see ‘Why might this be useful?’ below).

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

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 ...

In LCD backlight applications, a dc-to-ac inverter drives cold-cathode fluorescent lamps. The inverter's input comes from the display's power supply. Currently, it spans from 12 to 18 V. Pulse-width ...

Renewable energy continues to be a massive trend around the world. As methods for capturing wind, solar, and other forms of renewable energy have developed, the cost and efficiency of renewable energy ...
