We can convert the High voltage AC into Low voltage such as 5V, 6V, 9V, 12V DC, without using the Transformer, which is called Transformerless power supply. Here is the circuit diagram and explanation for transformerless power supply. News; Articles the schematic doesn't match the demonstrated circuit. D14 make up a bridge rectifier. 5V power supplies (or 5VDC power supplies) are one of the most common power supplies in use today. In general, a 5VDC output is obtained from a 50VAC or 240VAC input using a combination of transformers, diodes and transistors. 5V power supplies can be of two types: 5V regulated power supplies, and 5V unregulated power supplies. 5V regulated power supplies come in three styles. As a leader in the power supply industry, we realize that power is playing an increasingly critical role in your designs.

High current Power Supply, Switching Power Supply, Variable DC Power Supply Today I recommended the 045V 8A DC switching power supply circuit is a circuit that is capable of higher common linear circuit but it has a lot of detail. This power supply may not be as beastly as our 5V 20A supply but it does have the added benefit of being sealed and a smaller size. This supply great for powering a bunch of strands of Stringxels or a lot of servo motors. It can supply 5V DC up to 10 Amps, running from 110V or 220V power. In standby mode is main power supply blocked by positive voltage on the PSON pin through resistor R23 from secondary power supply. Because of this voltage is opened transistor Q10, which opens Q1, which applies reference voltage 5V from pin 14 IO1 to pin 4 IO1. This is 5V 3A Switching Regulator circuit by LM. 0 is simple switching power supply 3A step down regulator for power digital circuits. Sometimes we need to work on the car or travel outside the area. Amateur radio has been somewhat slow to accept switching power supplies for powering communication equipment. This is a pity, because switchers, as they are often called, offer very attractive features, like small size, low weight, high efficiency, and low heating. Analog Devices offers a wide range of switching regulators that operate in step up (boost), step down (buck), and inverting modes. These devices are capable of generating a fixed or adjustable output voltage, and offer up to 2 A of output current.
