A cycloconverter is a one stage AC/ AC converter that can
change the fixed frequency and amplitude of input voltage to a
voltage with variable frequency and amplitude without using
any reactive elements (like capacitor) and rectifier stage in its
structure. So the size of this converter is small and its lifetime
is long compared to two-stage frequency converters that use
energy storage elements in their structure. Therefore as
expected, this configuration could reduce both the volume of
the circuit and its loss and extend its lifetime, relibility and
efficiency [10]
