UPS and power inverters:

UPS - UPS or uninterruptible power supply uses an internal inverter to convert direct current to alternating current. Then store the power in the internal battery.

Power Inverter - The inverter is usually connected to an external DC power source to maintain continuous AC current. In this case, use a separate battery or battery to store energy.

Basic differences:

In the UPS, switching to standby power is fast and the inverter has a slight delay. This type of rest is acceptable for household appliances such as fans, lights and refrigerators, but it does not apply to sensitive devices such as computers and printers. Such delays can cause system crashes and data loss.

It uses the main power cord to power various appliances in the home or office. Unlike UPS, it does not plug directly into the device.

Technical differences:

UPS - In the UPS, the AC from the main power source is converted to DC. The DC continues to charge the battery. The DC output of the battery is fed into a sinusoidal waveform inverter that is converted to AC and supplied to the device.

The energy usually comes from the battery, so there is no gap during the mains power outage. The battery is now stopped charging, but the UPS continues to supply power until the battery is fully discharged.

Inverter - The power supply AC is supplied to the inverter and converted to DC to continuously charge the battery. The sensor and relay structure always monitors the ON or OFF state of the power supply.

In the event of a power failure, the relay actuator activates the inverter switch. All other operations are similar to UPS, but due to sensor and relay processes, there is a delay in activating the switch.

Circuit is not similar:

The circuitry used to fabricate the UPS is more expensive than the circuitry used in the inverter. This is why UPS systems are expensive.

UPS usually includes:

Rectifier or charger - The rectifier converts AC current from main current to DC current to charge the battery

Inverter - converts the battery's DC voltage to AC current for conversion to electrical equipment

Controller - It regulates the function of the rectifier and inverter.

The inverter includes:

Inverter - First it converts the power supply AC to DC for battery charging. Then, it changes the DC power from the battery to AC and then to the electronic device.

Controller - it manages inverter functions.
