UPS with silicon carbide is more energy saving and high efficiency
The economic mode of UPS has great advantages, but the latest development of silicon carbide technology could offset the economic advantages of the mode, the transistor is the traditional silicon controlled device for UPS, insulated gate bipolar transistor (IGBT) function more and more powerful and reliable.
The UPS with IGBT device has an obvious disadvantage, the faster the switching speed is (to obtain higher accuracy), the higher the power loss. This is mainly because the upper limit of the module efficiency is 96.8%, and the efficiency of the dual conversion UPS can be increased to 98%~99% theoretically by using SiC devices.
The synthesis of silicon carbide powder has been mass production since 1893, the initial cost of manufacturing IGBT by using silicon carbide is very high, but the energy-saving effect is very significant, and all these are not the key to the power grid load transfer, will not increase the risk of power conversion.
At the module level, silicon carbide has two advantages: Smaller chip size and lower dynamic loss. At the system level, these advantages can be exploited in many ways. Low dynamic losses lead to a significant increase in output power, providing an opportunity to reduce weight and volume. It is worth mentioning that power increase can be achieved without additional cooling capacity, because compared with SCR, reduce the loss brought silicon carbide practical, can get higher output power under the same cooling condition. Low power loss can improve energy efficiency, allowing the design of more efficient inverters, so the UPS will be more efficient energy saving.
Therefore, if silicon carbide is used, UPS can no longer be operated in an economy mode, you can even eliminate online interactive UPS, as the user is able to less than 1% of the energy loss, it can get the comprehensive protection of voltage and frequency protection, who will need UPS to run in the economic model?
