MULTILEVEL VOLTAGE CONVERTER Russian patent published in 2014 - IPC H02M7/42 H02M7/483 H02M7/501 

FIELD: electricity.

SUBSTANCE: voltage converter of power source includes multilevel power source voltage converter with possible output of multiple levels of the first voltage at one out of two output terminals via multiple conductive tracks; first power accumulator and first switching element with possible direct connection to the first output terminal and connection or disconnection of the first power accumulator to or from the first conductive track so as to combine voltage level of the first power accumulator with the first voltage level as a second voltage fed to second output terminal. With this topology, voltage rating of each poser semiconductor devices can be maintained at lower method without changes in the number of power semiconductor devices. In addition, VDRM is lower compared to standard topology. It allows for cost reduction and reliability improvement.

EFFECT: improved reliability.
