5V Switching Regulator, Very Simple Circuit

Switching Regulator for High Power Efficiency When you should regulate a high voltage to a much lower voltage, switching regulator must be the only choice. Fortunately,  a simple switcher integrated circuit chip is available, let you build a complete step-down switching regulator using five components. The switching regulator IC used in this circuit  is LM2575 series like we use in […]

DC to AC Inverter

DC to AC inverter is used to convert DC voltage source to an AC voltage source. DC AC inverter circuit works by switching the DC voltage source to make an alternating current  that flow to a transformer. Here is an example of  dc ac inverter schematic: This power inverter could generate 120 Watts power. A 15 fuse (as seen in […]

Variable Power Supply 1.2-55 Volt, Uses Switching Technology for High Efficiency

Designing wide range variable power supply using linear regulator is easy, but suffer terrible efficiency when it should regulate 60 Volt constant source  down to 5 Volt or lower, the efficiency would be 5/60 or 8.33% at maximum effort, really bad. Using switching technology, the efficiency can be kept around 70% , and can be higher for the lower input-output […]
