The simple circuit was designed using a 555 timer and pulse width modulation for controlling the speed of DC motor. The pulse width modulation (PWM) pertains to the process of switching the power ...

What is pulse width modulation? Pulse width modulation (PWM) is a powerful digital technique for controlling analog circuits with a microprocessor’s digital outputs. PWM is employed in a wide variety ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...

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 ...

Researchers at Sichuan University have proposed a four-level modulation strategy for dual three-phase open-winding PMSM drives, offering higher efficiency and lower current harmonic in such ...

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 ...

Mouser Electronics is now stocking the VIPer01 high-voltage converters from STMicroelectronics (ST). Part of the VIPerPlus family of high-voltage converters based on ST’s Bipolar-CMOS-DMOS (BCD) ...
