Frequency converters are essential devices that convert a given frequency to a different output frequency, offering flexibility for specific equipment needs. Frequency converters adjust the AC frequency using converter and inverter circuits, providing a stable and tailored energy supply. A manufacturer of frequency converters is crucial in this modern industrial world.
What Is a Frequency Converter?
A frequency converter is a device intended to convert an input frequency to any desired output frequency. The frequency of oscillation, or frequency, is the number of times a second that a radio wave or electric current completes a cycle. Direct current (DC) and alternating current (AC) are the two types of electric currents. Power sources in factories and residences usually provide AC at a set frequency. Occasionally, a machine or piece of equipment needs a different frequency than what the power source can offer. Frequency converters are employed to adjust the incoming current to the appropriate frequency.
Principle of Frequency Converters
Frequency converters use both inverters and converters to accomplish their tasks. An inverter transforms DC into AC, while a converter changes AC into DC.
- Converter Circuit: The entering AC is first converted into DC by the converter circuit. The converter circuit employs diodes to carry out full-wave rectification, guaranteeing that both positive values are extracted because AC is a sinusoidal wave with positive and negative values. The extracted current then flows via a capacitor. The job of a capacitor is to create a steady and continuous DC by periodically charging and discharging the current.
- Inverter Circuit: Subsequently, the current proceeds through an inverter circuit, which generates an AC with the desired frequency. It is achieved using transistors within the inverter circuit, allowing for the adjustment of the ON/OFF switching interval, which, in turn, varies the output frequency. Pulse Width Modulation (PWM) is a common technique in inverter circuits. PWM controls the output by managing the ON/OFF ratio of switches, offering advantages such as reduced power consumption and compactness. In an inverter circuit, the direction of current flow through the load is reversed when the switch is toggled ON/OFF. This technology, known as switching technology, is essential for generating alternating current.
- PWM (Pulse Width Modulation): One of the PWM control methods involves triangular wave comparison. A sine wave of the desired frequency (AC) is compared in this method with a high/low triangle-shaped wave known as a carrier using an operational amplifier. The switching control signal is ON when the sine wave exceeds the carrier. Conversely, when the sine wave falls below the carrier, it switches to OFF. This comparison is repeated to produce a switching control signal, resulting in a pulse wave output. AC voltage is supplied by switching DC using semiconductor switching devices.
