As engineers, there are many components and devices we use every day that we treat as black boxes. We only are concerned about the inputs and outputs of the black box, and this is acceptable provided ...

How pulse-width modulation (PWM) works with switch-mode converters. How PWM can be used in different power-switching applications. Switch-mode converters employ a power semiconductor switch (usually a ...

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 ...

What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...

Pulse width modulation is a technique used by smartphones when adjusting screen brightness. Essentially, the OLED display ...

Pulse Width Modulation is a topic that tends to give a lot of beginners trouble. [Daqq], whose nixie plasma ball we covered a few days ago, has a simple but effective PWM project that you should take ...

Pulse width modulation has been giving some users problems since the iPhone X. Fortunately, Apple is gearing up to tackle ...
