摘要： An inverter system (100) includes an inverter having a plurality of switching elements (108) arranged with at least three levels, where the inverter is configured to receive a direct current input and output an alternating current to three phases. The inverter system (100) also includes a controller (130) configured to determine a reference voltage angle based on a first voltage and a second voltage that are orthogonal components of a reference voltage and determine a sector of a space vector map of the reference voltage based on the reference voltage angle. The controller (130) is also configured to determine an active time pair of vector states associated with on-off states of the switching elements (108) to modulate between based on the sector and the reference voltage angle and output a carrier waveform for each of the three phases to control modulation of the switching elements (108) to achieve the reference voltage for the three phases.

摘要： The subject of the invention is a multilevel diode-clamped voltage inverter having a minimized number of transistors, enabling multilevel modulation of output voltage, created by modifying a classic NPC-type inverter.
The modification of the three-phase diode-clamped NPC inverter has been implemented by attaching to it an additional system composed of a capacitive divider constituting a serial connection of capacitors C3 and C4, and three legs, each including one controlled bidirectional switch (S13, S14 and S15), that connect a common connection point of the capacitors C3 and C4 to individual phase legs of the NPC inverter.
The inverter according to the invention is implemented in four versions. In a first and a second version, the capacitive divider of the additional system replaces one of the capacitors of the input divider of the NPC inverter, and in a third and a fourth version it is connected in parallel to one of the capacitors of the input divider of the NPC inverter.
The voltage between the phases of the system, which is the voltage difference of two legs of the system, can take values: Uin, 4Uin/3, Uin/2, Uin/4, 0, - Uin/4, - Uin/2, -4 Uin/3, - Uin, that is, at 9 levels.
