Abstract: There is described a power converter for transforming electrical power between direct current (DC) power and alternating current (AC) power. The power converter has a first stage comprising a first branch having a first pair of series-connected switches, a second branch having a second pair of series-connected switches, and a capacitor connected between the first and second branches: a second stage comprising a third branch having a first plurality of series-connected switches, a fourth branch having a second plurality of series-connected switches, and a plurality of capacitors connected between the third and fourth branches at respective connection points located between intermediate switches of the first and second pluralities of series-connected switches; and a connection branch coupling the first stage and the second stage.
