Every non-battery-powered electronic device requires converting offline ac power to some dc voltage for powering electronics. Nowadays, efficient conversion of electrical power is becoming an ...

[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 ...

In the second part of this two-part article, the authors describe how to determine the efficiency losses associated with passive components and how features offered by controller ICs can be used to ...

Modern personal computers (PC) use well designed, rich capacity and reliable switch mode power supplies (SMPS), which ought to be ideal for regular use in electronics hobby labs as dependable ...

Today's IGBTs are efficient and simply cost less. They're displacing MOSFETs in many SMPS applications up to and sometimes exceeding 200 kHz. Let's look at some of the application-related differences ...

Automotive incandescent bulbs have largely given way to more efficient, reliable, stylish, and even safer light emitting diodes (LEDs). LEDs turn on in a fraction of the time and are especially useful ...
