Portland, Ore. Electrical engineers at the University of Texas (Austin) have demonstrated what they claim is the world's smallest silicon modulator. The device features a photonic-crystal waveguide ...

Why PWM? Switch-mode converters employ a power semiconductor switch (usually a MOSFET) to drive a magnetic element (transformer or inductor) whose rectified output produces a dc voltage. Efficiencies ...

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 ...

Microchip announces the MCP1631 2.0 MHz, high-speed Pulse Width Modulator (PWM). The MCP1631 PWM provides a means to close the feedback loop in Switch-Mode Power Supplies (SMPSs) that use ...

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 basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED ...

ST’s STCH03 offline Pulse-Width Modulation (PWM) controller combines high integration with accurate constant-current output using primary-side regulation enabling economical mobile chargers, power ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...
