FIELD: electric engineering. ^ SUBSTANCE: invention is related to electric engineering and is intended for conversion of DC voltage into DC voltage of another value and may be used to match DC voltage source with load. In order to achieve technical result in the first version DC voltage converter, comprising n working controlled valves connected between the first inlet lead, being common with the first outlet lead and common points, n inductive accumulating elements and n main valves, which are connected serially into n circuits. Reverse controlled valve is connected parallel to each inductive accumulating element, being connected according to direction of inductive accumulating element current. Free leads of the main valves are connected to the second outlet lead. The novelty in this invention is the fact that common point of inductive accumulators and reverse controlled valves origins is connected to the second inlet lead via inlet controlled valve. The first inlet lead is connected by means of shunting valve to common point of inductive accumulator elements, reverse and inlet controlled valves. In the second version common point of origin of each i (where i=1,Ç, n) inductive accumulating element and i reverse controlled valve is connected to the second inlet lead via inlet i controlled valve. The first inlet lead is connected by i shunting valve with common point of i inductive accumulating element, i reverse and i inlet controlled valves. According to dependant claims, the second outlet lead is connected to common points of origins of inductive accumulating elements, shunting valves and also inlet and reverse controlled valves by additional reverse valves. Between outlet leads there are serially connected resistor and discharge controlled valve. Charge of inductive accumulators is carried out during connection of inlet controlled valves and working controlled valves. Discharge of inductive accumulating elements to load is carried out via main valves during disconnection of working controlled valves and inlet controlled valves. Available voltage on load is determined by duration of inductive accumulating elements discharge to load, which is interrupted during connection of appropriate reverse controlled valve. It is possible to recharge inductive accumulating elements by excessive energy of load via additional reverse controlled valves. It is possible to discharge inductive accumulating elements and load accumulators via discharge controlled valve and resistor. ^ EFFECT: expansion of functional resources, wider range of outlet voltage control and higher reliability. ^ 5 cl, 5 dwg |
