Patent ID: 7538449

Claim:
A circuit for at least one of an electric vehicle and a hybrid vehicle, comprising: at least one multi-phase machine with a first direct current unit that is at least one of a current source and a current sink; a second direct current unit that is at least one of a current source and a sink; an arrangement of power semiconductor components in a first and a second converter; each said first and said second converter further comprising: a corresponding number of half-bridge arrangements of two semiconductor switches; respective alternating current connections of each said semiconductor switches being connected to each other in phase direction and to connections of said at least one multi-phase machines whose direct current connections with a same polarity of respective converters are connected; wherein: a second polarity connection of each of said first and said second direct current units connects with each respective said converter; at least one flow control valve means for connecting a first polarity connection of said first direct current unit to a first connection of said first converter; at least a second flow control valve means for connecting a first polarity connection of said second direct current unit to a first connection of said second converter; said semiconductor switches, further comprise: at least one respective BOT switch, and; said switches of said negative connection and three half-bridge arrangements in said circuit, are mutual switches of said first and said second converter.
