1. A device for converting electrical power comprising:
a first voltage input;
a load comprising:
a first terminal; and
a second terminal; and
a plurality of primary switch modules connected in series across the first voltage input, wherein each primary switch module in the plurality of primary switch modules comprises:
a first voltage blocking capacitor connected to a first switch output; and
a second voltage blocking capacitor connected to a second switch output,
wherein the first switch outputs of each primary switch module in the plurality of primary switch modules are connected together with the first terminal and the second switch outputs of each primary switch module in the plurality of primary switch modules are connected together with the second terminal.
