Talk about common inverter power supplies
At present, the country's electricity energy is relatively tight, which seriously affects the use of every household appliance. In the daily life of urban and rural residents, the inverter power supply, which has never been known by residents, has become in short supply and has become a hot commodity in the recent market. Faced with a wide variety of inverter power supplies in the market, people are dazzled, especially most consumers who do not understand electronics are discouraged and difficult to choose. Power Supply has been producing and selling various common inverter power supplies for a long time, and has accumulated a lot of experience. It has a deep understanding of the performance, use, quality and practicality of common inverter power supplies, and hopes to be of some help to consumers when they buy effect.
At present, the more common inverter power supplies on the market include traditional inverter power supplies, digital inverter power supplies and UPS power supplies. The transformer of the traditional inverter is wound with ordinary silicon steel sheet, which not only consumes materials, is heavy and has low efficiency, but also has a no-load current of up to 0.7A~2A, which makes the battery with limited capacity waste serious energy. In addition, traditional inverters also have the following shortcomings: the output voltage is unstable, and electrical appliances are easily damaged; there is no short-circuit protection and undervoltage protection, which may easily cause the output power tube and the battery in the inverter to burn.
Digital inverter power supply is currently a relatively high-use inverter power supply among residents. It can completely solve various problems in the use of traditional inverters. It is a practical product that combines computer technology and power supply technology. A better power supply for backup power supply equipment. Most digital inverter power supplies use switching power supply solutions, and their pulse width modulation methods are voltage-type and current-type. The latter adjusts the output voltage while also adjusting the current, so it has a good The transient response capability can quickly respond to input and output changes and short-circuit or overload faults. It is not only efficient, but also flexible.
The rack inverter power supply with sine wave output is the best kind of backup power supply equipment. The output waveform is a pure sine wave, which is more perfect than the power supply waveform of a power plant. It can be used without considering the nature of the load. It is widely used in many fields such as electronic computers, networks, medical treatment and household appliances, and is used to protect data from loss and continuous power supply in important occasions. Plays a very important role.
The inverter power supply currently on sale by BWITT belongs to this type. It has a pure sine wave output. It uses a dedicated pulse width modulator (PWM) integrated circuit chip SG3525, which is composed of 8 high-power FETs to form a full-bridge switch. Circuit. Its no-load current is less than 100mA, the maximum output power is 1200W, the continuous working power is 1000W, and the efficiency is as high as 93%. It is fully qualified for the power requirements of daily lighting and various electrical appliances.
However, this is a basic electrical appliance, and its function is far less than this. In addition to the use of household appliances, the new technology developed by Powerwit can be used in large places, such as the national grid, computer rooms, and large power generation base stations.
