SOROTEC UPS

We believe that the development direction of the large server room of traditional  UPS  structure and micro module semi distributed UPS has been very clear, but these structures are more or less exist issues which efficiency and cost of UPS at this level are not optimal. Therefore, the city power supply technology, or the electricity directly supply to the server and other IT equipment, and do a good job of power failure protection, should be the next step in the development of data center power supply technology. With the rapid development of technology of the whole  power supply cabinet , we think the two will be combined together, the adoption of BBU built-in power down protection of city power supply plug box + frame battery scheme will be the next step of development direction.

The PV module is a DC source and will not generate electromagnetic interference itself. Some  inverter manufacturers cancel the DC EMI common mode inductance in order to reduce the cost. In fact, since the switching speed of the  solar inverter  is very high, which will produce large common mode interference current, if there is no EMI DC common mode inductance, the interference current signal will be transmitted to the DC cable and components, then the components will produce electromagnetic interference like an antenna, impact signals of photovoltaic system surrounding, such as with the antenna television and radio equipment will be bad to work. In order to increase the power generation, the series connected inverters are usually of two stage structure with wide input voltage range, single-phase 70-550V and three-phase 200-1000V. The first is a BOOST boost, to configure the boost inductor, the second is to configure the inverter circuit, filter inductor, boost induct...

The soft switching technology makes use of the resonance principle to change the current or voltage in the switching device according to the sine law. When the current is over zero, the device is turned off; When the voltage is zero, the device is turned on. Thus, the switching loss is reduced, and the problems of inductive shutdown and capacitive opening are greatly solved. When the voltage at the ends of the switch tube or the current flowing through the switch tube is zero, the switch is switched on or off so that there is no switching loss in the switch tube. The soft switching resonant converter is composed of inductors and capacitors. The resonant circuit increases the number of devices. The system becomes complex and the reliability is reduced; Since the power factor of  commercial solar inverter  is 1, the soft switching technique is only suitable for the DC-DC transform in the first stage, and the post stage DC-AC converter also requires electrical multilevel techn...

Power operation management. Redundancy technology is adopted in the power infrastructure of large data center room, and the construction is not a step in place. A large number of power equipment will be purchased step by step with the need of work. For example, the bank data center room built in three years, just after the initial purchase of new new electrical equipment installation, transport engineering equipment installation engineering equipment installation, integration and uninterrupted service for machine installation process, this process is not allowed to stop operation, live operation poses a threat to the safety of the management personal, but also increases the probability of error, can also cause serious key equipment downtime. There is a need for charged strict rules to avoid accident, double circuit simultaneous operation should be avoided when the UPS output power distribution unit (PDU) live line is connected in the dual way power supply system, ensure the security o...

Solar inverter  as a electronic equipment, its switching frequency is higher, the  series connected inverter  usually reaches about 20K, the current is relatively large, if you do not take measures, there will be a lot of electromagnetic interference. The usual 3 methods are shielding, filtering, and grounding. Shielding can effectively suppress the electromagnetic interference transmitted through space. The shield has two purposes, one is to limit the radiation of electromagnetic energy within the leakage control area, another is to prevent the external radiation of electromagnetic energy into the internal area, inverter adopts aluminum or steel conductor metal package. Filtering is the control of EMI conducted interference, usually using three devices to achieve: decoupling capacitors, EMI filters and magnetic components. The input and output of the inverter include X capacitor and Y capacitor, common mode inductors, magnetic beads, magnetic rings and other magnetic co...

If the power supply system can not output the specified current, the voltage exceeds the allowable fluctuation range, the noise voltage is higher than the allowable value time and lasts more than 10s, the system is judged to be a system fault. When the voltage, frequency or waveform distortion in the original AC system is beyond the specified range, and the duration is longer than 60s, it will be judged to be a fault. Therefore, in order to ensure the reliability of the telecom  outdoor DC power supply , the conditional telecom department should try to introduce 2 power input from two different places as far as possible, and set up the automatic switching device for the 2 way power input; the equipment should use high reliability switching equipment with high frequency, modular and hot plug type structure, so that it is easy to change, and configure backup equipment reasonably. No new technology or equipment shall be entered into the power supply system before being fully verified...

Wind  hybrid solar inverter system  refers to the combination of wind energy and solar energy, and uses the complementary characteristics of two kinds of energy in time to generate electricity and supply the wind energy and solar energy utilization mode. Wind energy and solar energy are renewable and clean energy sources, which are inexhaustible. Therefore, wind solar hybrid power supply system is a new type of green and sustainable generation mode. Wind solar hybrid power supply system is divided into two types: household type and centralized type according to their power load applications. Household type wind solar hybrid power supply system is suitable for household electricity demand, centralized type wind solar hybrid power supply system is suitable for the user more concentrated in the village, the town and other electricity needs, the number of users is generally a few households to hundreds of households. The wind solar hybrid power supply system is mainly compose...

In commercial application design, if the quality is guaranteed, it is easy to directly select the lowest price product after the comparation. At this time, the product with lowest price and common quality is often the winner, and the best quality products are unpopular. This is not bad for those soon to be abandoned or disposable electronic products, but how about designer choose such a  power supply for medical system ? The value of medical electronic products is high, and usually need to accomplish some key tasks. If the medical system fails, the consequences can be serious. The power supply for medical equipment must comply with safety, leakage, EMI-RFI radiation and protection requirements. These and related safety standards form a strict set of normative requirements. This kind of power supply must be in strict accordance with the insulation measures to prevent the patients and medical personnel from being electrocuted. EMC is also a key issue, including two aspects: how to r...
