This cycloconverter is a step down cycloconverter. It converts the incoming line frequency to a lower frequency by the use of SCRs. The two bridge type controlled rectifiers are connected in anti parallel direction via 4 ideal switches. The time period of the ideal switches control the output frequency and the voltage can be varied by the firing angle of the SCRs.
By using 4 switches the grounds of both the converter is isolated.

Yes, working on it.

Good effort, think some way to reduce the number of power switches
used. I guess there may be the way to eliminate the four central switches.
