The manufacturer of pure sine inverter 4000w tells you that with the rapid development of power electronics technology and the improvement of inverter control performance requirements in various industries, sine wave inverters have also been developed rapidly. The current development directions of inverters are mainly:

high frequency
High frequency refers to increasing the operating frequency of power switching devices, which not only reduces the volume of the entire system, but also has a good suppression of audio noise, and at the same time improves the dynamic response capability of the inverter output voltage. The pure sine inverter 4000w manufacturer tells you that the high-frequency power switching device corresponds to the high-frequency isolation transformer, and the application of the high-frequency isolation transformer has further reduced the volume of the entire system.
high performance
The effective value is the main parameter of the output voltage of the inverter. The effective value of the output voltage of the high-performance inverter is stable, and at the same time, it has high waveform quality and strong ability to adapt to nonlinear loads. The pure sine inverter 4000w manufacturer tells you that because the load carried by the inverter will change suddenly in many cases, the high-performance inverter requires a higher transient response performance of the output voltage. Another important parameter for the AC output voltage is the frequency. A good inverter requires not only a stable output voltage effective value, but also a stable frequency. Inverters with the above characteristics can be called high-performance inverters.
parallel technology
The current inverter technology can produce high-power products, but in high-power applications, once the inverter system fails, the system will be paralyzed. In a system composed of low-power inverters connected in parallel, the normal operation of each unit does not affect the work of other units, which greatly improves the reliability of the entire system.
miniaturization
Miniaturization is the result of high frequency, because the main way to miniaturize the inverter is to increase the operating frequency of the switching tube and use a high-frequency transformer. Another method is to improve the control method and optimize the spectrum of the SPWM wave so as to reduce the filter volume.
High input power factor
The pure sine inverter 4000w manufacturer tells you that many inverter systems use a certain topology circuit to convert DC power into high-frequency AC pulses, and then rectify to obtain the required DC voltage. The peak of the output current will reduce the input power factor, and improving the input side power factor can effectively solve the harmonic pollution caused by the inverter to the power grid.
Intelligence and digitization
The digitization of the inverter is not simply applying digital devices, such as FPGA and single-chip microcomputer, in the inverter, but the whole system relies on the computing power of digital devices and discrete control method to complete. The pure sine inverter 4000w manufacturer tells you that with the development of hardware, the processor speed is getting higher and higher, which promotes the development of inverters in the direction of intelligence and digitalization.
