This time we get a adjustable power supply with output voltages between and the maximum current of This is very useful for laboratory power supply or workshop power supply. This is Symmetrical regulated power supply and variable power supply 0 to 30V that can provide current uap to 2A and can be modified up to 5 A. Transformerless power supply | Electronics Forums A "transformerless power supply" uses an impedance to limit current, then a SHUNT, like a zener diode, to clamp the voltage. I don't think you would want to use a series regulator. Transformerless power supply with only Live wire | Page 2 ... When the switch is off the serial supply puts out very very little power, mainly the parallel supply does it then. When the switch is on obviously the parallel supply gets no input, but the current goes up so the serial supply kicks in with higher output. 12v 3a Transformerless Power Supply Projects Q A ... No because it's not practical. Take a typical transformerless power supply circuit: For 3A@12V C1 would need to be 47uF. The Shocking Truth About Transformerless Power Supplies ... Transformerless power supplies are showing up a lot here on Hackaday, especially in inexpensive products where the cost of a transformer would add significantly to the BOM. transformerless low current power supply ... Stack Exchange Use ST viper or similar as buck power supply. Alternatively, if your current is actually very low, use all your diodes as a rectifier. Alternatively, if your current is actually very low, use all your diodes as a rectifier.
