1. A hybrid switch for a power converter, comprising:
a first element and a second element, each comprising one or more switching devices of a first semiconductor type, and a third element comprising one or more switching devices of a second semiconductor type, wherein the second semiconductor type is different from the first semiconductor type, and wherein the first element is connected to a first control terminal, the second control element is connected to a second control terminal, and the third element is connected to a third control terminal, wherein the first element, the second element, and the third element are independently configurable; and
a controller connected to the first control terminal, a second control terminal, and a third control terminal and configured to activate one or more of the first element, the second element, and the third element in real time through the first control terminal, the second control terminal, and the third control terminal based on current and power defined by instantaneous operating conditions of the power converter, and wherein the controller is configured to adjust the semiconductor area ratios of switching devices of the first semiconductor type and the second semiconductor type.
