VARIABLE DC BOOST CONVERTER Russian patent published in 2023 - IPC H02M3/18 

FIELD: converter technology.

SUBSTANCE: invention relates can be used in press-forging equipment for energy recovery, as well as for other devices where it is required to increase the voltage while reducing the speed of the controlled element. The invention aims at achieving a voltage increase when the regenerative generators are slowed down, which allows increasing the voltage of the recovered energy, while compensating as much as possible for the decrease in energy production as the speed of the regenerative generators slows down. This is achieved by the fact that an adjustable DC boost converter comprising generators, a regenerative energy conversion device consisting of conversion modules and filter elements, according to the invention, a regenerative energy conversion device comprises groups of key elements that function with the ability to switch generators from parallel connection to serial and vice versa, and each conversion module comprises a key switching the serial connection of generators and a double key switching the parallel connection of generators.

EFFECT: more complete recovery, due to switching from parallel connection of generators to series by the end of the cycle, as well as the use of this converter in low-inertia mechanisms.
