Abstract:
A single-phase five-level active clamping converter unit and a converter. The single-phase five-level active clamping converter unit has three input ends and one output end, and also comprises: a suspension capacitor and a topological control portion. The topological control portion is connected to the suspension capacitor and the three input ends and one output end of the single-phase five-level active clamping converter unit, is connected to a plurality of control ends, and is suitable for the supply of at least eight operating modes under the control of a control signal accessing the control ends. In the single-phase five-level active clamping converter unit, a topological structure is easy to design, and is simple and convenient to control.
