The mains voltage is fed to the transformers of both channels(TR1,TR2)through the switch S1.A fullwave rectifier with middle point in which the diodes are replaced by tyristors TYR1-TRY6 is used.The direct voltage is filtered by the capacitor C and fed to the input Uin of the base contro unit CU(see fig.2).
Each half of the base secondary winding has three sections.The commutation of the tyristors TYR1-TYR6 is controlled by CU(outputs T1-T6):at the beginning,when the output voltage increases from0,the tyristors TYR1 andTYR2 are operating(fed by the first sections of the secondary winding)and the direct voltage has a minimal value.With the increasing of the output voltage tyristors TYR3 and TYR4 are switched on and the direct voltage also increase,because they are supplied by the second sections of the base secondary winding.(Tyristors TYR1 and TYR2 switch off automatically because their cathode voltage is higher than the anode one.)At much higher output voltage the tyristors TYR5 and TYR6 are switched on and the direct voltage achieves its maximal value.When the output voltage is decreasing,the tyristors switches off in inverse order.The described method of tyristor control ensures minimal voltage drop on the regulating transistor Q and respectively minimal power losses and maximal efficiency.
The output voltage is regulated by the potentiometer P1.For this purpose it receives a stabilized reference voltage from the output UREF through the switch S2,by which the output voltage could be switch "on" and "off".
