What Are the Methods of Supplying Power?

How a Double Conversion Online UPS Works

There are various types of UPS products. There are four main methods to supply power: passive standby topology, hybrid topology, double-conversion online topology, and parallel processing.


1. Passive standby topology

This method has less power conversion loss. As there is a slight momentary interruption during a power outage, it is ideal for applications such as surveillance cameras where momentary interruptions are not a concern.

2. Double conversion online topology

Stable power is constantly supplied through the inverter so it is a method with particularly high power supply quality. In the event of a power outage, power can be supplied without interruption. Ideal for base stations and communication servers.

3. Parallel processing topology

The bidirectional inverter improves the power quality on the power supply side because it compensates for the power factor and absorbs noise. In the event of a power outage, power can be supplied without interruption. Highly efficient and is ideal for power equipment such as production equipment.

4. SANYO DENKI’s original Hybrid topology

SANYO DENKI offers SANUPS E11B for our original Hybrid topology. This is a method in which the UPS automatically selects the optimum power supply mode. When the power supply situation is stable, the operation mode that prioritizes efficiency is used, and when the power supply situation is unstable, the power supply quality priority mode is used, achieving energy efficiency and saving cost. 

With high power supply quality and low power loss, it is ideal for control units of machine tools and elevators.
