UPS stands for Uninterruptible Power Supply, which is a device that provides emergency power to a load when the input power source fails.
UPS takes power from the main electrical supply and stores it in its battery
It then converts the stored power to the required voltage and frequency to supply to the load
UPS also provides protection against power surges and spikes
Example: APC Smart-UPS series
Rectifier and inverter sections are components of power electronics that convert AC to DC and DC to AC respectively.
Rectifier section converts AC to DC by using diodes
Inverter section converts DC to AC by using transistors
Rectifier section is used in power supplies, battery chargers, etc.
Inverter section is used in solar power systems, UPS, etc.
To convert 230V AC supply into 12V DC supply, a step-down transformer, rectifier, and filter capacitor are used in the circuit.
Use a step-down transformer to reduce the voltage from 230V AC to a lower voltage level.
Rectify the AC voltage using a bridge rectifier to convert it into pulsating DC.
Filter the pulsating DC using a capacitor to smoothen out the ripples and obtain a stable 12V DC output.
Ensure proper voltage r...
