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 ...

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 ...

Minor adjustments to switching frequency, thermal management, bias power, and inductor selection improves 48V buck converter ...

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 ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
