Abstract (en)

[origin: US2007014135A1] Voltage booster converter comprising a pair of input terminals A and B for connecting a DC input voltage Vin between these two terminals; a pair P<SUB>0 </SUB>of switches SB, SH in series connected by the switch SB to the input terminal B, the input terminal A being connected across an input inductor Lin to the connection point between the two switches SB and SH in series, each switch SB, SH comprising a control input so as to be placed simultaneously, one in an on state the other in an isolated state; a pair of output terminals C and D, for powering, by an output voltage Vout, a load Rout, the output terminal D being connected to the input terminal B; K other additional pairs P<SUB>1</SUB>, P<SUB>2</SUB>, . . . P<SUB>i</SUB>, . . . P<SUB>K-1</SUB>, P<SUB>K </SUB>of switches in series between the output terminal C and the free side of the switch SH with i=1, 2, . . . K-1, K, the two switches of one and the same additional pair Pi being connected across an energy recovery inductor Lr<SUB>1</SUB>; K input groups, Gin<SUB>1</SUB>, Gin<SUB>2</SUB>, . . . Gin<SUB>i</SUB>, . . . Gin<SUB>K-1</SUB>, Gin<SUB>K</SUB>, of Ni capacitors C of like value each in series, with i=1, 2, . . . K-1, K and Ni=i; K output groups, Gout<SUB>1</SUB>, Gout<SUB>2</SUB>, . . . Gout<SUB>i</SUB>, . . . Gout<SUB>K-1</SUB>, Gout<SUB>K</SUB>, of Mi capacitors C of like value each in series, with i=1, 2, . . . K and Mi=(K+1)-i. The switches of these other K additional pairs are controlled simultaneously by the first and second complementary control signals.
