1. The output voltage type of the inverter

The type of voltage produced by a frequency converter depends on the design of its output circuit. Depending on the design, the output voltage of the frequency converter can be AC or DC. Usually, the output voltage type of the frequency converter is AC. This is because alternating current has high transmission efficiency and is more suitable for long-distance transmission and changing the speed of the motor.

2. Application scenarios of frequency converter

Frequency converters are widely used in industrial production and can be used to control the speed of motors to ensure the stability and efficiency of the production process. Frequency converters have been widely used in machine tools, cranes, water pumps, fans and other fields, greatly improving the reliability and energy efficiency of equipment.

In conclusion, the type of voltage produced by a frequency converter can be AC or DC, depending on the design of the frequency converter output circuit. The working principle of the frequency converter is to convert fixed frequency and fixed voltage AC into adjustable frequency and adjustable voltage AC, which greatly improves the production efficiency and energy efficiency of the equipment.
