A single phase cyclo converter with mid point configuration is used for obtaining an output frequency of 1/3 times the input frequeny.Turns ratio from primary to upper seconday is 1/1 and to lower secondary is 1/2. The SCRs are so triggered as toobtain a symmetrical output voltage waveform.Sketch theoutput voltage and output voltage and output current waveform for resistive load for firing angle α=00 andα=300.Indicate the conduction of variousthyristors.
