Rectifier Circuit Diagram Without Transformer Uploadist

Generating Low voltage DC, from the 220v or 110v AC mains, is very useful and necessary in the field of electronics. Low voltage DC, like 5v, 6v, 9v, 12v, is used in electronics circuits, LED bulbs, toys and many household electronics items.Generally batteries are used to power them, but they need to be replaced time to time, which is not cost effective and also takes our time & energy.

a Maggiorina is a detached house in Italian style, located in the center of Agliano Terme. It consists of four newly renovated independent bright apartments with bedroom, bathroom, kitchen and balcony and/or terrace. The kitchen in each apartment is equipped for "self service/self made" cooking. If you prefer not to be the chef, we can.

Simple 12V 3A Power Supply Circuit

Voutput = 12V - 0.6V = 11.4V. Power dissipated by the diode = VI = minimal. The 1N4004 that can handled a RMS reverse voltage of 280V selected is a good selection. 7) Maximum power dissipated by zener diode without load = VI = 12 * 0.0146 W = 0.1752W. So 1/2W or up is good. 8) The specifications selected for the smoothing electrolytic.

A power supply without a transformer uses capacitive reactance theory to lower the incoming AC mains voltage. It should be remembered, in fact, that the electrical network supplies an alternating voltage of 230 VAC (or 110 VAC, depending on the country of residence) and the output voltage must be continuous and as leveled as possible.
