This Power supply directly connected to 220V AC, and using LM2575

The schematic diagram come from circuit: Transformerless power supply from 220V with LM2575 power supply. Go to that page to read the explanation about above power supply related circuit diagram.Transformerless power supply from 220V with LM2575
Is often required?to?supply electricity?to the?consumer?low?voltage 220V.? You?can?use?an external?adapter?- but?it's bad,?and?to?reduce the size of?the device?requires a?power supply?located?in the device. This 5v power supply used LM2995 to the converter?circuit?which?can be connected directly to?220V.? To?do this,? AC?converted?to DC?voltage?across the diode?bridge?VD1,? and?then?lowered?to?40V.? Above 40?V?we ...

6.8 Volt Transformerless Power Supply.
Quite a simple power supply unit can be built for half an hour. The scheme is designed for voltage and current of 6.8 V 300mA. The voltage can be changed by replacing the Zener D4 and, if necessary, D3. A ...

Transformerless power supply FET
The circuit shows a diagram of a simple transformerless power supply for transistor BUZ41A. Through the inclusion of the common-drain transistor VT1 NW capacitor charging to a voltage of about 3 smaller than the zener voltage of VD4. An alternating ...

Mains AC / DC Converter with SR03x
This is another Transformerless power supply.? IC voltage regulators for SR03x made ??by Supertex is connect directly to main voltage and get the output voltage to 3.3V and 5V chip for SR036 SR037 to 30mA output current. To use this ...

AT Power Supply Form Factor
AT means "Advanced Technology" and is the predecessor of today's standard ATX format. Previously, IBM developed the XT format. The AT-format is a standardized form factor, which determines how large the main board, how wide must be the spacing between ...
