摘要： A multilevel converter including, in particular, a voltage source, a current source, and a capacitor for each of its cells, and a controller. The controller evaluates any current difference between an observed current through the current source and a current requested by the current source. The controller also includes ON-time controller for taking into account the current difference, if any, and altering accordingly a duration of the first conduction state of all of the cells in the converter in a direction suitable for reducing the current difference. The controller also maintains all of the floating capacitors at their equilibrium voltage values.
