Voltage converter
A voltage transformer for the conversion of an input d.c. voltage into a three-phase a.c. voltage (U R , U S , U T ) in the mains frequency range having at least one inductor (L 1 , L 2 ) and having multiple switches (S 1 , . . . , S 9 ) controlled by a drive circuit (AST) in which a first transform...
