synchro converter and cycloconverter
SHIP POWER CONVERTERSRADAN1
The most commonly used motor drives are: DC converters, or SCR (Silicon Controlled Rectifier) for DC motors Cycloconverters (Cyclo) for AC motors, normally for synchronous motors Current source inverter type (CSI) converters for AC motors (synchronous motors)

The choice is to be made between using a synchroconverter and a cycloconverter. Sketch the circuit diagram of a synchroconverter noting on the diagram the modes of operation of the circuit when the propulsion machine is; Question: 3. a) A new vessel is to be fitted with an electric propulsion system using synchronous machines operating at
Cycloconverter: Applications & Types, Electrical4U
What is Cycloconverter A cycloconverter (also known as a cycloinverter or CCV) converts a constant voltage, constant frequency AC waveform to another AC waveform of a different frequency. A cycloconverter achieves this through synthesizing the output waveform from segments of the AC supply (without an intermediate DC link). The main

While a synchroconverter is able to provide an output frequency range typically up to twice that of the mains input (e.g. up to 120Hz), a cycloconverter is restricted to a much lower range.
Application of SuperSynchronization Speed Control
nal cycloconverter. By adding a converter with a output frequency of 0 Hz to 60 Hz and an output voltage of 6000 V to the stator terminal, the MG speed can be raised to 1650 rpm and the converter output power reach 120% of the motor rated power. As far as the highvoltage converter is
Advantages, Disadvantages of the Cycloconverter
If one of the SCR fails, the cyclo converter operates with distorted output. The cyclo converter generates high quality sinusoidal waveform for low output frequency whereas the static inverter generates square waveform for low output frequency (< 10 Hz).
