How to Convert Frequency

A device that converts one frequency to another is called a frequency converter. It’s frequently utilized in power supply systems, signal processing, and motor speed control.

Typically, the procedure consists of three primary steps: converting the input to direct current (DC), storing the DC power, and then converting the DC back to alternating current (AC) at a different frequency.

Frequency Calculation Method

• Input Frequency (f_in): The frequency of the input AC signal.
• Output Frequency (f_out): The desired frequency of the output AC signal.
• Voltage and Current Conversion: The input AC voltage is first converted to DC using a rectifier. The DC voltage is then converted back to AC with the desired frequency using an inverter.

The calculation of the output parameters can involve complex circuitry and control algorithms, but here we provide a simplified conceptual outline.

Example Calculations of Frequency Conversion

Ex. 1: Simple Frequency Conversion

• Input Frequency (f_in): 50 Hz
• Desired Output Frequency (f_out): 60 Hz

Step-by-Step Calculation:

• Rectification:

The AC input at 50 Hz is converted to DC using a rectifier.

• DC Link:

A DC link (capacitor or inductor) smooths out the rectified DC signal.

• Inversion:

The smoothed DC signal is then fed into an inverter.

The inverter converts the DC signal back to AC at the desired frequency of 60 Hz.

Ex. 2: Voltage and Frequency Conversion

• Input Voltage (V_in): 230 V, 50 Hz
• Desired Output Voltage (V_out): 110 V, 60 Hz

Step-by-Step Calculation:

• Rectification:

Convert the 230 V, 50 Hz AC to DC.

If the rectifier output is not pure DC, additional filtering is applied to smooth the DC voltage.

• DC Link:

Use capacitors or inductors to filter the DC voltage.

• Inversion:

Convert the filtered DC voltage to 110 V AC at 60 Hz using an inverter.

Control circuits ensure the output voltage is regulated to 110 V and the frequency is maintained at 60 Hz.

Ex. 3: Frequency Conversion with Variable Speed Drive

• Input Frequency (f_in): 50 Hz
• Desired Output Frequency (f_out): Variable (e.g., 30 Hz to 70 Hz)
• Application: Motor speed control

Step-by-Step Calculation:

• Rectification:

Convert the 50 Hz AC to DC.

• DC Link:

Smooth the DC signal with filtering.

• Inversion with Variable Frequency:

Use a variable frequency drive (VFD) to convert the DC signal back to AC with a controllable frequency.

Adjust the output frequency dynamically to control motor speed.

Example Calculation:

• Set the VFD to 25 Hz if the motor needs to run at half its typical speed, which is 50 Hz.

The principles involved in altering the frequency of electrical impulses are illustrated by these examples. In practical application, factors like power consumption, process efficiency, undesired noise, and heat control are also significant. More complex frequency changers may include additional methods like as pulse-width modulation (PWM) to achieve finer frequency control.

Units of Frequency Measurement

Units of frequency measurement indicate the repetition frequency of an event. Hertz (Hz) is the most often used unit for this, while other units are employed in other contexts. Below are a few of the principal units:

• Hertz (Hz):
  • The standard unit of frequency.
  • 1 Hz = 1 cycle per second.
  • Used in most general applications such as sound waves, radio waves, and electrical signals.
• Kilohertz (kHz):
  • 1 kHz = 1,000 Hz.
  • Commonly used in radio broadcasting, audio engineering, and telecommunications.
• Megahertz (MHz):
  • 1 MHz = 1,000,000 Hz.
  • Often used to measure frequencies of radio waves, TV signals, and computer processor speeds.
• Gigahertz (GHz):
  • 1 GHz = 1,000,000,000 Hz.
  • Used for very high-frequency applications such as microwave communications, satellite transmissions, and modern computer processors.
• Terahertz (THz):
  • 1 THz = 1,000,000,000,000 Hz.
  • Used in advanced technologies like terahertz imaging and spectroscopy.
• Revolutions per minute (RPM):
  • Not a direct unit of frequency in Hz, but often used to describe rotational speeds.
  • 1 RPM = 1/60 Hz.
  • Commonly used in mechanical contexts like engine speeds and turntables.
• Beats per minute (BPM):
  • Common in music to describe tempo.
  • 1 BPM = 1/60 Hz.
• Cycles per second (cps):
  • An older term, now largely replaced by Hertz.
  • 1 cps = 1 Hz.
• Radians per second (rad/s):
  • Used in angular frequency measurements.
  • 1 rad/s=1/2π Hz.
• Frames per second (fps):
  • Used in video and animation to describe the number of frames displayed per second.
  • 1 fps = 1 frame per second = 1 Hz.

It is crucial to understand the operation of these measures and how to convert them across different formats in fields such as electronics, cellular phones, and music technology.

Frequency Unit Conversion Table

Here’s a chart showing how different units of frequency compare:

Frequency Unit	Symbol	Definition	Equivalent in Hz
