(Summary description)
　　The variable frequency power supply is a power supply whose output frequency and voltage can be adjusted within a certain range of a pure sine wave through AC→DC→AC conversion from the alternating current in the mains. It is different from the frequency conversion speed controller used for motor speed control, and it is also different from the ordinary AC stabilized power supply. The ideal AC power supply is characterized by stable frequency, stable voltage, zero internal resistance, and a pure sine wave (without distortion); the variable frequency power supply is very close to the ideal AC power supply. Therefore, the advanced developed countries increasingly use the variable frequency power supply It is used as a standard power supply to provide the best power supply environment for electrical appliances and facilitate the objective assessment of the technical performance of electrical appliances.

　　The variable frequency power supply is a high-performance precision power supply designed with IGBT inverter output technology and advanced microprocessor control. It has the protection of over current, short circuit, over voltage, overload, etc. and alarm fault display functions to ensure the use of electrical equipment and frequency conversion Power safety. It has the characteristics of strong load adaptability, good output waveform quality, good man-machine interface, simple operation, small size and light weight. Pure sine wave output, variable frequency power supply with adjustable output voltage and frequency provides AC power needed by electrical equipment.

　　Application purpose and field of variable frequency power supply:

　　Due to the inconsistent power grid indicators of various countries in the world, export electrical appliance manufacturers need power supplies to simulate the power grid conditions of different countries, providing engineers with pure and reliable applications in design and development, production line testing and quality assurance product testing, life, over-voltage/low-voltage simulation testing, etc. , Low harmonic distortion, high stable frequency and steady-state sine wave power output; users of imported original electrical appliances and equipment also need to transform and convert my country's power grid to ensure the normal operation of imported electrical appliances and equipment; meet avionics And military equipment needs.
