A cycloconverter or a cycloinverter converts an AC waveform, such as the mains supply, to another AC waveform of a lower frequency, synthesizing the output waveform from segments of the AC supply without an intermediate direct-current link.
Cyclo converters are used to fixed frequency AC signal in to variable frequency AC signal. They are used in the induction heating, and in high power applications.

For decrease the rectifier number
At first, there was cycloconverter with thyristors, then matrix converter with IGBT...
u refer cycloconverter and matrix converter
Converter is AC to DC. Inverter is DC to AC
Step Down cycloconverters generally Lower the input frequency to a desired value.This has many applications such as activities requiring low frequency namely electric traction systems where simple DC commutating machines are provided with frequencies of order of 16 hz.

The types of dc-dc converters are the ones with isolation and the ones without isolation. Isolation makes sence only into very high or very small ratios of Vin / Vout. Vin is the Voltage input and Vout is the voltage output of the converter. The isolation is applied between input and output circuits by using a transformer. The main types of converters are buck,boost and buck-boost (without isolation) and Cuk, Flyback and Forward (with isolation).
There are two ways. If you want to increase the frequency by a huge amount and you want to do it on a permanent basis, install more magnets. An alternator that has one pair of field magnets and that turns at 3600rpm will generate 60-hertz electricity. If you put two pair of field magnets in it and turn it 3600rpm, it will generate 120-hertz electricity, and so on and so forth. (The other side of that is, if you want a certain frequency of electricity, the more pairs of magnets you install the slower the alternator has to turn. Install four pair of magnets in the generator, and you only need to run the engine at 900rpm--which makes it much quieter, a big advantage if the generator belongs to the army.) If you just need to adjust it a little, simply rev up the engine. If you have a generator that makes 60hz power at 3600rpm, accelerating the generator to 3660rpm will cause it to make 61hz electricity.
I'm going to assume you're referring to the frequency of AC (Alternating Current) and I'm going to assume that you're asking because you have some device that wants 50Hz and you are faced with a 60Hz supply. That is a lot of assumptions but you didn't give a lot of information.It is possible but you'd have to convert the 60Hz AC to DC then back to 50Hz AC. It would involve some expensive equipment. I'm not aware of a one-box solution but you could piece together a system with an AC-DC battery charger, adequate storage batteries, and a DC-AC power inverter. Depending on your application, you might be better off replacing the equipment that won't run on 60Hz.Before running off and spending your money on this, check the labels for your equipment. The label on my laptop power supply says it accepts 110vac-240vac at 50/60Hz. If you're going to run into problems it would most likely be with electric motors.
