The 3 kVA Online UPS is a high-performance uninterruptible power supply system designed to deliver continuous, clean, and regulated power to mission-critical equipment. With true double-conversion technology, it provides seamless protection against power interruptions, voltage fluctuations, surges, and frequency variations—ideal for IT networks, industrial automation, medical devices, and sensitive electronics.

An IGBT Online UPS (Uninterruptible Power Supply) refers to a type of UPS system that utilizes Insulated Gate Bipolar Transistor (IGBT) technology. IGBTs are semiconductor devices used for switching power in many modern power electronic systems due to their efficiency and fast switching capabilities.

Here's how an IGBT Online UPS generally works:

1. AC to DC Conversion: The UPS takes incoming AC power from the mains and converts it to DC power using a rectifier circuit. IGBTs are often used in the rectifier stage due to their ability to handle high voltages and currents efficiently.

2. Battery Charging: While the UPS is receiving AC power, it also charges its internal battery bank. This ensures that the batteries are maintained at optimal levels for use during power outages.

3. DC to AC Conversion: The UPS continuously inverts the DC power from the battery into clean AC power using an inverter circuit. IGBTs are commonly used in the inverter stage as well, as they can efficiently switch high currents at high frequencies.
