FAQ

What are the differences between the inverter and the frequency converter?

Functionality

Frequency Converter: A frequency converter is a device that changes the frequency of an alternating current (AC). It is primarily used to control the speed of AC motors by varying the frequency of the electrical power supplied to the motor.
Inverter: An inverter is a device that converts direct current (DC) into alternating current (AC). It can also adjust the frequency of the output AC, making it versatile for various applications, including converting battery power to household AC power.

Frequency Adjustment

Frequency Converter: This device specifically includes components to adjust the frequency of the AC output. The output frequency can be varied as required by the application.
Inverter: While an inverter's primary function is to convert DC to AC, it often includes the ability to adjust the output frequency. However, some inverters may provide a fixed output frequency depending on their design and intended use.

Conversion Process

Frequency Converter: The conversion process involves converting the incoming AC power to DC and then converting this DC power back to AC at the desired frequency and voltage. This process is known as AC-DC-AC conversion. Initially, the AC input is rectified to DC, which is then inverted back to AC with the required frequency and amplitude. This allows precise control over the frequency and voltage of the output power.
Inverter: The conversion process involves several steps. Initially, the inverter converts AC power to DC (if the input is AC). Then, it converts the DC power back to AC at the desired frequency and voltage. This process is known as AC-DC-AC conversion, which includes rectification (AC to DC) followed by inversion (DC to AC).

Applications

Frequency Converter: Commonly used in industrial and commercial settings to control motor speeds and improve energy efficiency.
Inverter: Widely used in renewable energy systems, such as solar power installations, where it converts the DC output of solar panels into AC power for household or grid use. It is also used in uninterruptible power supplies (UPS) and various portable power applications.

Everything feels good

Everything feels good. I tried another brand and it had humming noise from the electronics. This 300 watt pure sine wave inverter doesn't have noise. Just very little noise but totally acceptable.
