A frequency converter is a machine that converts a received frequency to an arbitrary frequency. Frequency is also called frequency of oscillation, and refers to the number of times an electric current or radio wave repeats its waves per second. Electric current can be either direct current (DC) or alternating current (AC). Power sources in homes and factories are basically alternating current sources, which supply current of a fixed frequency. However, some machines may require a higher or lower frequency than the power supply. In such cases, a frequency converter is used to convert the frequency to an arbitrary one.
Frequency conversion is necessary in many aspects of our lives.
For example, there are differences in frequencies in different regions. The current supplied from an electrical outlet is fixed at 50 Hz in eastern Japan and 60 Hz in western Japan. Many home appliances have built-in frequency converters so that they can be used in the same way in different regions. Frequency converters are also essential when building factories overseas, since the frequencies used may be different.
Furthermore, some machine tools require low or high frequency power supplies, so they need to be converted from a 50 Hz or 60 Hz power supply to the required frequency.
Frequency converters can convert to any desired frequency by applying an electric current. Here, we will tell you the principle of how the frequency is converted.
First, an inverter or converter is used as the structure. An inverter is a device that converts DC current to AC current and a converter is a device that converts AC current to DC current. The original AC current is converted to DC current by passing current through the converter circuit. Since AC current is a sine wave, there are positive and negative values, but by causing full-wave rectification with a diode in the converter circuit, both positive values can be extracted.
Next, the extracted current is passed through a capacitor. The capacitor is repeatedly charged and discharged to smooth the current and create a smooth DC current.
Finally, the current is passed through an inverter circuit to produce an alternating current changed to an arbitrary frequency. The inverter circuit contains transistors, which can produce waves of varying frequency by adjusting the on-off switching interval.
