SOROTEC UPS

1.To have super environmental adaptability Unlike commercial  UPS , which is placed in data centers and server rooms under strict control of temperature, humidity and cleanliness,  industrial UPS  is often difficult to ensure stable temperature and humidity in the industrial environment. In addition, in special industrial occasions, the air in the environment may also contain corrosive gases, which will affect the normal operation of power supply equipment and reduce its performance over a long period of time. Therefore, this requires industrial UPS to have super environmental adaptability, and to cope with the test of harsh environment with comprehensive high-performance performance. 2.To be able to effectively eliminate all kinds of radio disturbances Power grid pollution in industrial application site is very serious, and it often faces the situation of power supply shortage and frequent accidents. Precision production equipment in industrial production line always has very s

The only way to improve the efficiency of the  inverters  is to reduce the losses. The main losses of the  solar inverters  come from IGBT, MOSFET and other power switches, as well as magnetic devices such as transformers and inductors. Loss is related to the current and voltage of components and the process adopted by the selected materials. The losses of IGBT are mainly conduction loss and switching loss. The conduction loss is related to internal resistance and current passing through the device, switching loss is related to switching frequency of the device and DC voltage of the device. The main loss of inductance is copper loss and iron loss. Copper loss refers to the loss caused by the resistance of inductance coil. When the current is heated by the resistance of inductance coil, part of the electric energy is transformed into heat energy, which is called copper loss because the coil is usually wound by insulated copper wire. Copper loss can be calculated by measuring short-

There are currently three technical routes. First, space vector pulse width modulation (SVPWM) is used to reduce the loss. Secondly, silicon carbide materials are used to reduce the internal resistance of power devices. Third, three-level, five-level multi-level electrical topology and soft switching technology are adopted to reduce the voltage at both ends of power devices and the switching frequency of power devices. 1.Space Vector Pulse Width Modulation (SVPWM) SVPWM is a fully digital control method, which has the advantages of high utilization rate of DC voltage and easy control. It is widely used in  inverters . With high utilization of DC voltage, lower DC bus voltage can be used under the same output voltage, which reduces the voltage stress of power switching devices, reduces the switching losses on devices, and improves the conversion efficiency of inverters to a certain extent. In space vector synthesis, there are many combinations of vector sequences. Through differe
