Most switch-mode power supplies rely on a PWM (pulse-width-modulated) output that is controlled via voltage feedback. A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

GaN switches promise higher efficiency and higher power density in SMPS. This article discusses the readiness of this technology and its challenges, and provides an outlook on being a replacement for ...

The proper installation of switch-mode power supplies in control systems is crucial to guarantee 24/7 availability and reduce problems associated with grounding faults, harmonic distortion, and other ...

How switch-mode power supplies changed the power-supply design space. The isolation factor in power supplies: galvanic isolation vs. non-isolated. Most common non-isolated topologies. This series ...

[Hesam Moshiri] has built a variable switch-mode power supply over on hackaday.io. When prototyping a new circuit, often the goal is to get a proof-of-concept working as soon as possible to iron out ...

Too often maintenance engineers are concerned about the DC voltage and current draw from their Switch Mode Power Supply (SMPS) in the control panel. With a typical power supply you will need to have a ...
