ENERGY CONVERSION EQUIPMENT FOR DC POWER SUPPLY SYSTEMS Russian patent published in 2019 - IPC H02J7/35 

FIELD: electrical engineering.

SUBSTANCE: proposed equipment uses a static semiconductor converter with two inputs, in the push-pull bridge circuit of the power section of which two chokes are used, their first terminals are connected to the diagonal of the bridge, and their second terminals are combined. In the circuit the task of reducing the weight and size is solved by connecting a solar battery through a diode directly to the terminals combining two parallel branches of the bridge, connecting the diagonal bridge nodes through the diodes directly to the positive terminal of parallel-connected filter capacitors and loads. To improve the reliability of operation, the battery is connected through a bidirectional converter to the combined terminals of the chokes. And the entered bidirectional converter carries out shutdown of the storage battery, regulation and restriction of its current.

EFFECT: invention can be used in uninterrupted power supply systems of direct current without galvanic isolation of the load and two sources, one of which can accumulate electrical energy.
