Frequency and voltage stabilization function of variable frequency power supply
The inverter power supply that undergoes AC → DC → AC conversion is called a variable frequency power supply, which is different from the variable frequency speed control controller used for motor speed regulation and also different from ordinary AC stabilized power supply. The main function of a variable frequency power supply is to convert the existing AC power grid into a stable and pure sine wave power supply with the required frequency. The characteristics of an ideal AC power supply are frequency stability, voltage stability, zero internal resistance, and a pure sine wave voltage waveform (without distortion). Variable frequency power supply is very close to ideal AC power supply. Therefore, more and more advanced developed countries are using variable frequency power supply as a standard power supply to provide a good power supply environment for electrical appliances and facilitate objective assessment of their technical performance.
Variable frequency power supply is a frequency conversion device composed of the entire circuit of AC, DC, AC, and filtering, which has been widely used. Variable frequency power supply can not only simulate and output the power grid indicators of different countries, but also provide pure, reliable, low harmonic distortion, high stability voltage and frequency sine wave power output for export electrical appliance manufacturers in design, development, production, testing and other applications. Variable frequency power supply is a very ideal AC power supply that can output the voltage and frequency of any country's power grid.
A frequency converter is composed of circuits such as AC straight current and AC (modulated wave), and its standard name should be frequency converter speed controller. The waveform of its output voltage is a pulse square wave with many harmonic components. The voltage and frequency change proportionally at the same time and cannot be adjusted separately, which does not meet the requirements of AC power supply.
