Ac To Dc Transformer Circuit Diagram
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.

Power supply without transformers. By Electronic Circuit Saturday, May 07, 2011. Transformerless Power Supply - circuit bidding supply up to more or less 20mA next to 12 volts. It uses capacitive reactance in its place of resistance; and it doesn't generate very much heat up.The circuit draws about 30ma AC. continuously management a fuse and.
Transformerless power supply How to make a power supply without transformer YouTube
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.

12V DC Power Supply without Transformer. These are 12V DC power supply circuit which designed without transformer (trafo). These circuit use capacitive reactance instead of resistance; and it doesn't generate very much heat.The circuit draws about 30ma AC. Always use a fuse and/or a fusible resistor to be on the safe side.
How to make 24v power supply without transformer easy step by step with circuit diagram YouTube
As the name suggests, a transformerless power supply circuit uses no inductor or transformer when providing a low DC from the mains' high voltage Alternating Current. It works by making a high voltage capacitor drop the AC primary current (120V or 230V) to a low current level (12V, 5V, or 3V).

Capacitive power supply with more power efficiency. An efficient power supply that can deliver 9V DC at 100 mA is shown in Fig. 8. 230V AC is stepped down to 24V AC by capacitor C1. This low-voltage AC is rectified by a bridge rectifier to give 20V DC. Capacitors C2, C3 and C4 eliminate ripples from the DC and store current to stabilise the output.

The diagram shown below is a simple transformer less power supply. Here 225 K(2.2uF) 400 volts X rated capacitor is used to drop 230 volt AC. Resistor R2 is the bleeder resistor that remove the stored current from the capacitor when the circuit is unplugged. Without R2, there is chance for fatal shock if the circuit is touched.
