摘要： A method for controlling modulation wave and a three-phase three-wire three-level circuit are provided. The method for controlling modulation wave is applied in the three-phase three-wire three-level circuit. Three bridge arms of the three-phase three-wire three-level circuit correspond to three modulation waves. The three-phase three-wire three-level circuit is controlled by comparing said three modulation waves and a carrier wave. The method for controlling modulation wave includes: obtaining a primary modulation wave from said modulation waves based on currents corresponding to each phase of the three-phase three-wire three-level circuit; and adding a shifting quantity to said three modulation waves such that the primary modulation wave is shifted to a peak value, a valley value, or a middle value between the peak value and the valley value of the carrier wave.

摘要： A converter includes a first bridge arm, a second bridge arm, a switch circuit and a voltage clamp circuit. The first bridge arm includes a first switch unit and a second switch unit that are electrically coupled in series at an output terminal. The second bridge arm includes two voltage sources that are electrically coupled in series at a neutral point terminal. The switch circuit is disposed between the neutral point terminal and the output terminal. The voltage clamp circuit is electrically coupled to the output terminal, the neutral point terminal, and one of a positive input terminal and a negative input terminal, and is configured to clamp voltage across the switch circuit.

The first bridge arm includes a first switch unit and a second switch unit that are electrically coupled in series at an output terminal. The second bridge arm includes two voltage sources that are electrically coupled in series at a neutral point terminal. The two switch units are electrically coupled in series at a common connection terminal, and are arranged between the neutral point terminal and the output terminal. The voltage clamp circuit is electrically coupled to the output terminal, the common connection terminal, the neutral point terminal, and one of a positive input terminal or a negative input terminal, and the circuit is shared by the two switch units to clamp voltages across the two switch units.
