What is variable frequency power supply
After the AC-DC-AC conversion double inverter power supply is called variable frequency power supply, it is different from the frequency conversion speed controller used for motor speed regulation.
It is also different from ordinary AC regulated power supply. The main function of the variable frequency power supply is to transform the existing AC grid current into a stable, pure sine wave power at the desired frequency. The ideal AC power supply is characterized by stable frequency, stable voltage, zero internal resistance, and pure sine wave (no distortion). The frequency conversion power supply is very close to the ideal AC power supply. Therefore, more and more advanced countries
The source is used as a standard power supply in order to provide the best power supply environment for electrical appliances and facilitate the objective assessment of the technical performance of electrical appliances.
There are two major types of variable frequency power supplies: transistor amplification and PWM switching. DP series variable frequency power supply, with microprocessor as the core, PWM method, sinusoidal pulse width modulation and other technologies, making the stand-alone capacity up to 1000KVA, and increasing the output of the isolation transformer
Machine stability, with strong load adaptability, good output waveform quality, good operation waveform, easy operation, small size, light weight, etc.
Point, with short-circuit, over-current, over-voltage, overheating and other protection functions to ensure reliable operation of the power supply.
