Line double-conversion UPS

Line double-conversion UPS




This is the power range of 10kVA power over the most common type of UPS. Shown in Figure 4-line double-conversion UPS, chart, in addition to the main power path is the inverter (not the AC main power), the other with the same back design.

In the double-conversion online design, the input AC power failure and will not activate the switch, because the input AC power has been a backup battery, backup battery to the output by the inverter. Therefore, the input AC power failure, no time-line running state conversion.

In this design, the battery charger and inverter to convert the entire load power, and generate more heat as a result of reduced efficiency.

This UPS provides ideal power output performance. The reliability of this design over other designs, but the continued depletion of lower power components such reliability, but also throughout the life cycle cost UPS, due to low power efficiency and energy consumption accounts for a large part. In addition, the large battery charger input power is usually obtained by nonlinear, may interfere with building power supply system or cause the failure of standby generators.





Delta Conversion On-line type UPS



Delta Conversion On-line type UPS design is a newer design, which is 10 years ago to introduce the technology, it overcomes the double-conversion online design shortcomings for 5kVA to 1.6MW power range of applications. And double-conversion online design similar, Delta conversion online type UPS is always provided by the power inverter load voltage. However, the additional Delta Converter also to the inverter output power. In the AC power failure or tampering of the case, this design behavior shown by double-conversion online design exactly the same.

Delta conversion topology to understand the energy efficiency of a simple method is to examine from the 4th floor of the building to the 5th floor of the energy required for transportation of parcels, as shown in Figure 6. Delta conversion technology through the delivery of parcels by distance is only the beginning and the end of the difference between the amount of (Delta), and thus saves the energy. -Line double-conversion UPS converts DC to AC power, and then from DC can be converted to AC; and Delta converter to move the power output from the input.

Delta Conversion On-line style in the design, Delta converter has a dual role. The first role is to control the input power characteristics. Sinusoidal input to obtain its power to minimize the clutter reflected to the device. This ensures that the generator system with high efficiency and compatibility, while reducing the heat distribution system and system losses.

Delta conversion-line double conversion UPS provides online design with exactly the same output characteristics. However, the input characteristics of the two designs are usually not the same. Delta conversion online design provides dynamic control, the input power factor correction, while the traditional solutions do not appear inefficient use of filter questions. The greatest advantage is greatly reduced energy losses. In addition, the input power control also allows UPS to all units compatible with, Delta conversion-line technology is the only patent-protected core UPS technology, a large number of UPS suppliers can not apply the technology.

In a stable state, as compared with the double-conversion design, Delta converter allows UPS to a much higher efficiency of the power to the load.
