FIELD: electrical engineering; conversion of ac, 220 V supply voltage into fractional-power supply for feeding low-power loads. SUBSTANCE: thyristor changer has diode bridge rectifier connected to ac voltage supply through capacitor; connected to diode bridge output are series-interconnected transformer primary winding and gate-control thyristor. Output voltage can be steplessly regulated from no voltage to rated value by varying thyristor turn-on angle. EFFECT: simplified design. 1 cl, 3 dwg
