POWER CONVERSION DEVICE Russian patent published in 2022 - IPC H02P27/14 H02M7/48 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to devices for generating an unlocking signal and actuating an energy converter. The effect is achieved in that the power conversion device contains a modulation block with a fixed pulse sequence, which is configured to access tables storing pulse sequences that determine the corresponding command voltage levels corresponding to phase data for each modulation ratio, and with the possibility of generating a trigger signal based on modulation command ratio and control phase, wherein the device is configured to actuate the power converter based on the enable signal, wherein the fixed pulse train modulation unit is also configured to search for the proper post-transition table reference position when performing a pulse train transition and ensure that the command level is followed voltage to the command voltage level of the post-transition pulse train.

EFFECT: ensuring the transition of the pulse train without a current pulse.
