AC to AC Converter These types of power electronic converters are used to convert the alternating current waveforms of specific magnitude and specific frequency into alternating current waveforms with different magnitude and different frequency, as the signal remains AC, hence this converter is termed as AC to AC converter. To operate a few devices and machines we require some specific voltage with specific frequency which can be obtained using AC to AC converters. By regulating using the AC to AC converter we can regulate the speed of induction motors. There are different types of AC to AC converters which are classified based on different criteria. Types of AC to AC Converters • Cycloconverter • DC link based AC to AC Converter • Matrix Converter These AC to AC converters are again classified into various types such as step up cycloconverters, step down cycloconverters, single phase to single phase cycloconverters, three phase to single phase cycloconverters, three phase to three phase cycloconverters, envelope cycloconverters, phase controlled cycloconverters, CSI converters, VSI converters, sparse matrix converters, very sparse matrix converters, ultra sparse matrix converters, and hybrid matrix converters. Let us discuss about a simple AC to AC converter circuit diagram in this article along with practical application of AC to AC converter. Download Educar Sin Castigos Ni Recompensas Pdf.

Simple AC to AC Converter can be considered as a Simple AC to AC converter circuit diagram. The frequency of AC power can be changed using cycloconverters and these cyclconverters can also be used to change AC power magnitude in specific applications. Typically, AC to AC converter consists of DC link which increases the cost of system, reduces the efficiency in the conversion process. So, AC to AC converter without DC links such as cyclconverters are preferred for converting AC to AC power. Simple AC to AC Converter Circuit Diagram (Cycloconverter) The simple AC to AC converter circuit diagram is shown in the above figure which is termed as single phase to single phase cycloconverter.
It consists of two limbs, one limb is for positive half cycle and other limb for the negative half cycle of the. Hence, they are called as negative limb (N-converter) and positive limb (P-converter) which consists of four thyrsitors in each of these limbs. The frequency of the input signal is varied by applying triggering pulse to these thyrsitors of AC to AC converter appropriately. Thus, by varying the triggering pulse we can vary the output power frequency. Practical Application of Simple AC to AC Converter Circuit Block Diagram by Edgefxkits.com The block diagram of single phase induction motor speed control using AC to AC converter is shown in the above figure which consists of various blocks. These blocks include power supply block which is used for providing power supply to project kit. The microcontroller block with interfaced with AC to AC converter through the Opto-isolator.
There are slide switches which are interfaced with microcontroller and are used for selecting the mode (F, F/2, and F/3). The motor can be made to operate at three speeds by selecting the appropriate mode using these slide switches. Based on the selected mode, the microcontroller gives triggering pulse to the thyrsitors of AC to AC converter and thus, the output power frequency is varied. Based on the speed vs frequency relation of motor,. Do you know what is?
