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 fundamental technique in power electronics that facilitates the efficient control of power delivery by modulating the width of voltage or current pulses. This method ...

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 ...

Continental has been granted a patent for a method of switching electronic components using pulse-width modulation signals. The method controls output signals through control signals, adjusting them ...

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 ...

A switching-mode power supply is configured to have two modes: a normal mode and a measure mode. To determine a compensation factor to compensate the switching-mode power supply in the normal mode, ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

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 ...
