The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

A novel full-wave rectifier turns an audio power amplifier into a simple modulator, that is then used to modulate an ...

In some power-supply applications, the pulse-width-modulator (PWM) controller is powered up from an auxiliary winding tapped off the power stages transformer (Fig. 1).

In this paper, we propose a new methodology to enhance SoC signal integrity with respect to power/ground voltage transients, without degrading its performance. The underlying principle of the proposed ...

Here is a Power Supply Guard circuit that can be used as a protective device in power supply boxes. This type of Spike protection circuit is present in the multi socket switch boards used to connect ...

Supply Modulator (SM): A circuit that regulates the voltage provided to a power amplifier, optimising its performance in line with the varying envelope of the transmitted signal.

This article presents a fast-transitioning power supply modulator (PSM) which is proposed to be used in envelope tracking(ET) systems for high bandwidth millimeter-wave RF power amplifiers (PA) ...

For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies us… ...

My two file servers have redundant power supplies with all ps's plugged into a UPS. The UPS's are on the same circuit. I want to plug one ps/UPS from each server into another circuit for an ...

Capacitors C1 and C2 are power-supply bypass capacitors to help isolate the 555 timer (U1) from noise on the power line. Likewise, C3 and C4 bypass op-amp U2.

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable pr… ...

In this video, we will showcase a universal input (85V-260V AC) to 12V-3A DC Flyback power supply, delivering 36W of stable output power. The design uses an affordable PWM controller and an external ...
