Overview of Uninterruptive Power Systems (UPS)

necessary, when line power is available. This type of supply is sometimes called an "offline" UPS. In the normal mode, the load is directly supplied with the utility power supply at the same time the charger charges the battery. In the event of a blackout, the battery will supply power to the inverter that will supply AC power to all connected ...

Transformerless Power Supply

One of the major problems that is to be solved in an electronic circuit design is the production of low voltage DC power supply from AC to power the circuit. [[wysiwyg_imageupload::]]The conventional method is the use of a step-down transformer to reduce the 230 V AC to a desired level of low voltage AC. The most suitable and low cost …

How to Convert a Car Battery into a Power Outlet without Inverter

This will ensure that the converter can handle the power output of the battery and provide a stable power supply for your devices. Safety and Preparation Before you begin to convert a car battery into a power outlet without an inverter, it is important to take the necessary precautions to ensure your safety and the safety of those around you.

Regulated Vs. Unregulated Power Supply

Finally, the power supply sends power through a regulator to even out the voltage. The regulator prevents highs and lows of electricity from reaching the power supply''s output, providing clean, even power for the most sensitive of devices. Due to needing fewer steps and parts, linear power supplies cost less than switching.
