Best Online UPS

An Online UPS is a type of uninterruptible power supply that utilises either a double or delta conversion technology. With double conversion, network equipment does not receive electricity directly from the AC outlet. Instead, AC power travels to a rectifier, where it becomes DC power. Next, it travels to the battery, and then an inverter. After inversion back to AC, the power is delivered to equipment. With this online UPS device process, computing equipment receives continually clean power. With delta conversion, a certain amount of power is sent to run computers, routers, and other equipment directly. This creates an energy-efficient online UPS system where some of the power skips the processing steps.

If an electrical failure occurs, an Online UPS system maintains consistent current flow for the protection of network equipment. Upon fluctuation or failure, the rectifier within the UPS is automatically bypassed, and power is sourced from the battery until restoration occurs. The online UPS circuity is seamless. This is why Online UPS systems cost more than units in the offline or line-interactive UPS categories.

Types of Online UPS

Double Conversion Online UPS

A double-conversion on-line UPS converts power twice. First, AC input, with all of its voltage spikes, distortion, and other anomalies, is converted into DC. A double-conversion on-line UPS uses a capacitor to stabilize this DC voltage and store energy drawn from the AC input. Second, DC is converted back into AC that is tightly regulated by the UPS. This AC output can even have a different requency from the AC input. All of the power provided to the load equipment goes through this double-conversion process when AC input is present. 

When AC input goes out of a specified range, the UPS draws power from its battery so that the UPS output is not affected. In many double-conversion on-line designs, this transition inside the UPS between AC input and battery takes several milliseconds. Again, it is the capacitor in the “DC link” (see Figure 5) that provides stored energy to the inverter during these transitions. So, even though there is a brief interruption in power going into the “DC link,” the UPS output voltage is unaffected and continuous.

Delta Conversion Online UPS

Delta conversion online UPS systems operate by using a delta conversion topology, which offers enhanced efficiency and reliability compared to traditional double conversion UPS systems. Delta conversion UPS systems are capable of handling a wide range of input voltages and provide superior power protection for critical electronic equipment.

Delta Conversion Online UPS is a modern innovation that eliminates the disadvantages of the traditional double conversion online UPS. The enhancements are based on having a delta inverter and allowing bidirectional power flow. Today, this design is the only major uninterruptible power supply technology protected by patents and is unlikely to be offered from a broad range of UPS suppliers. Also, delta conversion online units are available in the market from 5 kVA to 1 MVA.

Benefits of Using Online UPS

• Continuous Power Protection: Online UPS systems provide continuous power protection, ensuring that critical devices remain operational even during extended power outages.
• High Efficiency: Online UPS systems offer high efficiency and reliability, making them ideal for protecting sensitive electronic equipment from power-related issues.
• Voltage Regulation: Online UPS systems regulate voltage fluctuations and surges, ensuring that connected devices receive clean and stable power at all times.
• Scalability: Online UPS systems are highly scalable and can be easily expanded to accommodate growing power requirements.

How Online UPS Works

Online UPS systems operate by converting incoming AC power from the utility source into DC power, which is then used to charge the internal batteries and power the inverter. The inverter then converts the DC power back into clean and stable AC power, which is supplied to connected devices. This continuous double conversion process ensures that the load is always powered by the UPS, providing seamless protection against power disturbances.
