Frequency Converter Faqs

Q1) What is a frequency converter used for?

What is a frequency converter? Basicly put, frequency converters are a power conversion device. The frequency converter converts a basic fixed-frequency, fixed voltage sine-wave power (line power) to a variable-frequency, variable-voltage output used to control speed of induction motors.

Q2) How do you convert one frequency to another?

Frequency transformers are utilized for changing over mass AC power starting with one frequency then onto the next, when two adjoining power matrices work at various utility frequency. A variable-frequency drive is a kind of frequency transformer utilized for speed control of AC engines, for example, utilized for pumps and fans.

Q3) How do you convert 50Hz to 60Hz?

Initially, a rectifier changes over the 50Hz AC voltage into DC voltage. The DC voltage relies upon the RMS of AC voltage. At that point an inverter is received to change over the DC voltage into 60Hz AC voltage. The geography of single stage consecutive converter is as demonstrated in the figure.

Q4) What is difference between frequency converter and VFD?

Frequency converter yields the AC capacity to unadulterated sine wave after the change of AC→DC→AC, the yield frequency and voltage can be changed inside a specific reach. It is not the same as the variable frequency drive (VFD) utilized for engine speed guideline, and furthermore not quite the same as the basic AC managed power supply.

Q5) How does the frequency converter work?

A Rotary Frequency Converter uses a generator to deliver a genuine yield sine wave at the ideal recurrence – similar as the force organizations. A Static Frequency Converter uses a double conversion transformation measure with a rectifier that changes the AC contribution to DC. From that point forward, the inverter changes over it back to an AC yield.

Q6) How do you increase the frequency of a generator?

To change the output frequency to 50 Hz for a similar generator arrangement, the motor speed should be decreased. Likewise, for generator, a motor speed produces output of 60 Hz. Decreasing the motor speedand output will be 50 Hz.

Q7) What is the difference between 220V 50Hz and 220V 60Hz?

There is a small difference between 50 Hz and 60 Hz systems, as long as the equipment is designed appropriately for the frequency. The main difference is that 60Hz systems usually use 110V (120V) or somewhere around for the main power supply, while 50Hz systems tend to use 220V, 230V etc.

Q8) What is the advantage of converting a frequency?

By running your machines at a more slow, more proficient speed, frequency converters will assist it with running much better for more, which can lessen the requirement for support and the costs that accompany it.
