As engineers, you use many components and devicesevery day that you treat as black boxes. You are concernedonly about the inputs and outputs of the blackbox, and that approach is acceptable provided ...

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 ...

Feel like breaking out of your streaming-induced vegetative state but can’t seem to break the binge-watching cycle? Maybe you’re a candidate for this exercise bike that controls how much Netflix you ...

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 ...

When an application requires changes in motor speeds to meet its objectives, a variable frequency drive (VFD) is often the first thing that comes to mind. This is for good reason—VFDs are typically ...

The novel methodology is reportedly able to track global maximum power point and reduce power losses in partially shaded PV systems by up to 33%. It uses a backstepping controller (BSC) algorithm to ...

Some of the UK’s most serious sprayer operators are turning to pulse-width modulation (PWM) systems in a bid to improve accuracy and slash chemical costs, apparently unperturbed by its £25,000 price ...

Mounted on a buck-convertor test board, the chip converts an input voltage of 48V to an output voltage of 1V, with a pulse width modulation signal of 1 MHz. The achievement looks to leverage on imec’s ...
