<p>The invention relates to electrical engineering, in particular to power supplies which comprise high-frequency converters for converting direct current into direct current and can be used for producing power supplies exhibiting high electrical characteristics. The inventive power supply is provided with an electrochemical current source which comprises at least one element with an anode and cathode which are separated by an electrolyte, a bypass capacitance connected to the electrical output of the electrochemical current source, a DC-DC converter with a key element, a control unit and an inductive power storage unit connected to the bypass capacitance, wherein the control unit is designed so as to be able to adjust the switching frequency of the key element within a range from 5 kHz to 1 MHz. The specific impedance of the anode ranges from 0.01 to 1.6 Ohm·cm2, the ratio between the bypass capacitance C? and the anode differential capacitance Ca is determined by an expression C?/Ca=from 0.5 to 5.0. The input resistance of the DC-DC converter ranges from 0.5 to 5.0 Ohm. The DC-DC converter may comprise a planar transformer, and the inductive power storage unit is connected to the output winding of the planar transformer.</p> |
