Claim 12:
13. The power converter of claim 1, wherein
the control unit is configured to operate the power converter in a high conversion ratio operation mode;
in the high conversion ratio operation mode, an operation cycle comprises a first modified main state, a second modified main state and a modified peak state;
within the first modified main state, the power converter exhibits
a first current path from ground through the inductor to the output; and
a second current path with
1) A sub-path from the input through the second lower capacitor to the output; and
2) a sub-path from the input through the first lower capacitor to the output;

within the second modified main state, the power converter exhibits
a first current path with
1) A sub-path from ground through the first lower capacitor, through the inductor to the output; and
2) a sub-path from ground through the second lower capacitor, through the inductor to the output;

within the modified peak state, the power converter exhibits
a first current path from the input through the inductor to the output; and
a second current path with
1) A sub-path from the input through the second lower capacitor to the output; and
2) A sub-path from the input through the first lower capacitor to the output.
