Title: SINGLE-PHASE FIVE-LEVEL ACTIVE CLAMPING CONVERTER UNIT AND CONVERTER
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 (I1, I2 and I3) and one output end (Io), and also comprises: a suspension capacitor (Cs) and a topological control portion. The topological control portion is connected to the suspension capacitor (Cs) and the three input ends (I1, I2 and I3) and one output end (Io) 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.
