by Paul Golata, Mouser Electronics Gone are the days when lights were standalone devices whose sole purpose was to illuminate a particular area. The rise of connectivity and data-dependency in our lives means the role of luminaires is changing. Connected lighting systems (CLSs), using light-emitting diode (LED) technology and Internet of Things (IoT) connectivity, now […]
Why use optocouplers in electronics?
Optocouplers not only protect sensitive circuits but enable an engineer to design a variety of hardware applications. Optocouplers can avoid a great deal of cost in replacing components by protecting them. However, optocouplers are more sophisticated than fuses. Optocouplers also make it convenient to control the connection between two circuits by connecting and disconnecting them […]
What are diodes? A quick refresher
A diode is a passive component made with semiconductor materials (a chip) that conducts current flowing in one direction but does not conduct current flowing in the opposite direction. The symbol for a diode (to the right in Figure 1) looks something like an arrow pointing in the direction of the forward current. Current flows […]
A simple and inexpensive ideal-diode MOSFET circuit
by Crutschow When you parallel a battery with another battery or other source, the batteries are often required to be back charged. This can be done with standard diodes, but that gives close to a half volt drop — even with Schottky diodes. This is especially problematic with low-voltage batteries, where that drop is a […]
Learning SMPS the hard way
By Syed Tahmid Mahbub, EDAboard.com forum member SMPS is the toughest section in power electronics. For this subject, you require additional knowledge for choosing the active and passive parts used in SMPS circuits. The special type of parts often required in power electronics (i.e. for low-frequency applications) may not be suitable in the case of […]
