Topology
A problem in the combination of a "double conversion" UPS and a generator is the voltage distortion created by the UPS. The input of a double conversion UPS is essentially a big rectifier. The current drawn by the UPS is non-sinusoidal. This can cause the voltage from the AC mains or a generator to also become non-sinusoidal. The voltage distortion then can cause problems in all electrical equipment connected to that power source, including the UPS itself. It will also cause more power to be lost in the wiring supplying power to the UPS due to the spikes in current flow. This level of "noise" is measured as a percentage of "Total Harmonic Distortion of the current" (THD(i)). Classic UPS rectifiers have a THD(i) level of around 25–30%. To reduce voltage distortion, this requires heavier mains wiring or generators more than twice as large as the UPS.
There are several solutions to reduce the THD(i) in a double conversion UPS:
Power factor correction (PFC)
An alternative solution is an active filter. Through the use of such a device, THD(i) can drop to 5% over the full power range. The newest technology in double conversion UPS units is a rectifier that doesn't use classic rectifier components (thyristors and diodes) but high frequency components. A double conversion UPS with an IGBT rectifier and inductor can have a THD(i) as small as 2%. This completely eliminates the need to oversize the generator (and transformers), without additional filters, investment cost, losses, or space.
Digital Technology: Microprocessor based digital control ensures pure and perfect sinewave output delivering accurate voltage and clean power. It increases speed and efficiency of power conversion and facilitates communication interface between the machine and the user.
Double Conversion Topology (With Galvanic Isolation): This UPS topology provides complete isolation from the incoming distribution system and the load at the UPS output. Continuous protection of load is provided from the Inverter, whether it originates from AC-input supply or the battery. Wide input voltage tolerances, precise regulation of the output voltage and frequency and a no-break transfer to bypass mode are the other main benefits with double conversion.
Active power factor correction: The advanced technology used in the rectifier section with active power factor correction reduces power consumption by 30%. It reduces input current as well as voltage harmonics and helps to considerably downsize the generator or utility power rating. It has a soft-start feature to avoid in rush current.
