CONSTANT VOLTAGE STEP-DOWN INVERTER Russian patent published in 2015 - IPC H02M3/00 H02M3/135 

FIELD: electrical engineering.

SUBSTANCE: this gadget incorporates three extra diodes and one transistor. Emitter of the latter is connected with cathode of the first extra diode and anode of the second extra diode and second output of current limiting throttle. Transistor collector is connected with second diode cathode and with positive output terminal. First diode anode is connected to common assembly combining the negative input and output terminal. Third diode anode is connected with first output of current limiting throttle while its cathode is connected with input terminal positive output. Variation of transistor operation on-off ratio allows variation or stabilisation of output voltage level relative to input voltage as well as adjustment of power supply charge current of accumulated active load power.

EFFECT: control of flow of recuperated power.
