Most isolated, offline SMPSs (switched-mode power supplies), including flyback, forward, and resonant, must operate at input voltages of 90 to 260V rms. Some cases even use line-to-line voltages of ...

The voltage regulators from the 78xx-series are found in many analogue power supplies. It seems, then, somewhat superfluous to say much more about them. But on the other hand, it can be very useful to ...

Switch-mode regulators include the buck (step-down) and the boost (step-up), forward and flyback topologies, as well as the SEPIC, hysteretic and multiphase converters. Two basic IC topologies are ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...

Making a dc voltage from an ac source means you will have to rectify the ac voltage to get a dc bus. One difference compared to a dc-dc converter is that you can use a linear power supply with an ac ...
