How Double Conversion UPS Works

Double Conversion UPS technology operates by constantly converting incoming AC power to DC and then back to AC power. Here’s a breakdown of how it works:

  • Incoming AC Power: The UPS takes in the incoming AC power and converts it to DC power using a rectifier. This DC power charges the batteries and powers the inverter.
  • DC Power: The DC power from the rectifier charges the batteries to ensure they are always ready to provide backup power in case of an outage. Additionally, this DC power supplies the inverter.
  • Inverter: The inverter then converts the DC power back into AC power. This AC power is what supplies the connected devices with a clean and stable power source. This protects them from power disturbances like surges, sags, and spikes.
  • Continuous Process: This process of converting AC power to DC, routing it through the batteries and inverter, and then back to AC power is continuous while the UPS is running. It ensures that the output power is always regulated and free from any electrical anomalies.
  • Instantaneous Switchover: Double Conversion technology offers seamless protection by instantly switching over to battery power when it detects any interruption or fluctuation in the incoming AC power. This ensures that connected devices remain powered without any disruption.

In essence, a Double Conversion UPS provides a reliable and consistent power supply by transforming incoming AC power into stable DC power and then converting it back to AC power for the connected equipment, safeguarding them against power fluctuations and outages.
