摘要：In a power supply circuit for supplying stabilized relatively low DC voltages toat least first and second load circuits as operating power voltages for the latter withoutthe use of a power transformer, and in which the first and second load circuits areconnected in series to each other across a DC voltage source supplying a relatively highDC voltage for dividing the latter between the first and second load circuits in accordancewith their respective impedances; an additional DC voltage souce is connected betweenboth load circuits to produce an additional DC voltage varying in response to variations inthe voltage applied across the first load circuit, for example, as a result of variations inthe impedance of the latter, and to apply the additional DC voltage to the second loadcircuit so as to compensate for the variations in the voltage applied across said secondload circuit as a result of the variations in the voltage applied across the first load circuit,thereby to stabilize the relatively low DC voltages applied to both load circuits.
