FIELD: electricity. ^ SUBSTANCE: voltage stabilisation device is provided with possibility of being connected to the source of alternating electric power supply and voltage control, which is supplied to certain chosen circuits the loads of which will gain advantages from voltage control. Device includes pulse width modulation or autotransformer with switched phase angle which is compact and light enough to be connected to standard electric consumer device which has separate circuits, i.e. those ones the loads of which take advantages from voltage control and those ones which do not take advantages so that the former can be operated with the device, thus providing the operation at stable and decreased voltage. Operating temperature of autotransformer is controlled with temporary increase of output voltage of autotransformer in case of overheating. ^ EFFECT: reducing energy consumption and increasing service life of appliances connected to the device. ^ 2 cl, 2 dwg |
