Abstract: It is pointed out that there are several possibilities to realize an AC variable speed drive with cycloconverters. The motor can be an asynchronous or a synchronous type and the cycloconverter can be operated with or without circulating current. The author presents the characteristics of the different solutions and compares their performance in rolling mill main drive applications.

These types of Cycloconvertes are formed by using 3 threephase to single cycloconverters linked together to the load and is used in AC machine systems. Two basic configurations are wye and delta. Output of these converters can be connected in wye and delta. The phase of output voltages are 120 o shifted. The circuit diagram is shown below.
