Due to the high integration, compact overall structure and large heat dissipation, the  hybrid inverter  requires high temperature, humidity and dust content in the installation environment. When installing the  solar inverter , it must provide a good operating environment for the  inverter . The working ambient temperature of the inverter is rated at 40 ℃. If the ambient temperature is higher than 40 ℃ ~ 50 ℃, the rated current must be reduced. Otherwise, the temperature rise of the device will be too high, which will increase the possibility of device damage (especially IGBT power module), and have a great impact on normal and safe operation. If the working environment of the inverter fails to meet the requirements of the inverter on the working environment, it will cause high failure rate of the inverter, affect the long-term, reliable and safe operation, resulting in unnecessary economic losses. Therefore, the following matters should be paid attention to in the...

Manufacturers and users of  UPS power supply system  have long noticed the matching problem between generators and UPS, especially the harmful effects of current harmonics generated by rectifiers on  power supply systems  such as voltage regulators of generators and synchronous circuits of UPS. Therefore, the technicians designed the input filter and applied it to UPS, and successfully controlled the current harmonics in UPS application. These filters play a key role in UPS compatibility with generators. In fact, all input filters use capacitors and inductors to absorb the destructive current harmonics at the UPS input. The design of the input filter takes into account the percentage of all possible harmonic distortion inherent in the UPS circuit and at full load. Another benefit of most filters is to increase the input power factor of UPS with load. However, another consequence of the application of input filters is to reduce the overall efficiency of UPS. Most...

Switching power supply  is to use electronic switching devices (such as transistors, field effect transistors, thyristors, etc.) to make electronic switching devices “turn on” and “turn off” continuously through control circuits, so that electronic switching devices can modulate the input voltage, thus realizing DC/AC, DC/DC voltage conversion, as well as adjustable and automatic voltage stabilization of the output voltage. There are generally three modes of switching power supply: fixed frequency and pulse width mode, fixed frequency and variable pulse width mode, and variable frequency and pulse width mode. The former mode is mostly used in DC/AC  inverters  or DC/DC voltage conversion, while the latter two modes are mostly used in switching regulated power supply. In addition, the output voltage of switching power supply also has three working modes: direct output voltage mode, average output voltage mode and amplitude output voltage mode. Similarly, the former is m...

Nowadays, many people like to talk about “power quality”. There are many products of power quality, such as  SVG ,  APF and three-phase unbalanced regulator, which have become “hot-selling products”. But what are the benefits of improving power quality for people? Improving power quality is of great significance to the safe and economic operation of power grid, ensuring the quality of industrial products and the normal conduct of scientific experiments, and reducing energy consumption. Power quality is directly related to the overall benefits of the national economy. Good power quality is undoubtedly beneficial to the operation of electrical equipment, but the adverse impact of poor power quality on the operation of power system has not attracted enough attention. From the point of view of harm degree, the harm of some power quality problems is destructive. For example, the overvoltage caused by harmonic resonance in lightning impulse, capacitor and cable switching ofte...

In the fault area of the  outdoor cabinet , the cabinet is usually made of cold rolled steel or alloy, which is used to store computer and related control equipment. It can provide protection for storage equipment, shield electromagnetic interference, arrange equipment in an orderly and orderly manner, and facilitate the maintenance of equipment in the future. Cabinet is generally divided into server cabinet, network cabinet, console cabinet and so on. As the user of cabinet, you must know the fault area of cabinet. Fault area 1: below the cabinet (outside the cabinet) The area below the rack and above the floor is difficult to manage because leveling bolts or casters vary in size and manufacturer and height. There will be a lot of uncontrolled air in this area. If the area can be properly sealed, it can produce very high benefits. Usually, there is no solid baffle under the cabinet due to the need to connect wires or nets. This will also lead to air leakage in the area, bec...

With the progress of power electronics technology and control technology, domestic  active harmonic filter  has replaced imported products in various major projects. In 2012 alone, the sales of domestic APF products have exceeded the imported brands by five times. Active power filter will eventually replace the traditional passive filter because of its huge technological advantages, powerful functions and declining price. During the development of APF, modular APF equipment has gradually replaced traditional cabinet APF with its advantages of small size, convenient installation, high integration, stable operation and convenient expansion. In the next five years, the combination of modular APF and  static var generator  (SVG) will become the most powerful solution in power quality industry, and will be widely recognized by the market.

Solar panels belong to photovoltaic devices (mainly semiconductor materials), which produce current by photoelectric effect after irradiation by light. Because of the properties and limitations of materials and light, the generated current is also a wavy curve. If the generated current is directly charged into the battery or directly supplied to the load, it will easily cause damage to the battery and load, and seriously reduce their life. Therefore, we must first feed the current into the  solar charge controller , use a series of special chip circuits to digitally adjust it, and add multi-level charge and discharge protection to ensure the operation safety and service life of the battery and load. When power is supplied to the load, the current of the storage battery is first flowed into the solar charge controller, and then into the load after its adjustment. The purpose of this method is to stabilize the discharge current, to ensure that the battery is not over-discharged, and...

In the process of using  UPS power supply system , people tend to unilaterally think that storage battery is maintenance-free and pay no attention to it. However, data show that the proportion of  UPS  mainframe failure or abnormal operation caused by battery failure is about 1/3. Therefore, it is more and more important to strengthen the correct use and maintenance of UPS batteries for prolonging the life of batteries and reducing the failure rate of  UPS systems . In addition to the selection of regular brand batteries, we should start from the following aspects to correctly use and maintain batteries: 1.Maintain appropriate ambient temperature Ambient temperature is an important factor affecting the life of battery. The optimum ambient temperature required by battery manufacturers is between 20℃ ~ 25 ℃. Although the discharge capacity of batteries is improved with the increase of temperature, the cost is that the life of batteries is greatly shortened. Acco...

To optimize the efficiency and reliability of  solar power generation system , a relatively new method is to use micro-inverters connected to each solar cell module. Each solar cell is equipped with a single micro-inverter, which enables the system to adapt to changing loads and weather conditions, thus providing the best conversion efficiency for a single solar cell and the whole system. The concept of micro-inverters has a long history, but it did not attract people’s attention at first. In recent years, with the development of solar power technology and technological progress, micro-inverters are very attractive. The photovoltaic power generation system with micro-inverters can simplify wiring, which means lower installation costs, higher efficiency of the solar power generation system, and shorten the time required to recover the initial investment. Many chinese manufacturers of  solar on grid inverters  are mainly engaged in the development of high-power...
