Abstract

Stack device having voltage compensation. In some embodiments, a switching device can include switching elements connected in series between a first terminal and a second terminal, with a first end switching element being connected to the first terminal and a second end switching element being connected to the second terminal. Each switching element can have a parameter such that the switching elements have a distribution of parameter values that decreases from the first end switching element for at least half of the switching elements to a minimum parameter value corresponding to a switching element between the first end switching element and the second end switching element. The minimum parameter value can be less than the parameter value of the second end switching element, and the parameter value of the first end switching element can be greater than or equal to the parameter value of the second end switching element.
