The four-switch three-phase inverter (FSTPI) is the fault-tolerant topology of the six-switch three-phase inverter (SSTPI), and the maximum output voltage is limited in the linear modulation region. Therefore, an overmodulation strategy for FSTPI is presented, based on virtual voltage vector and superposition principle, in order to improve the utilization of the DC voltage, enhance the output capacity...
It has been a hot issue and also a difficulty to study the fault tolerance of multilevel converters. The topology changes to eight-switch three-phase inverter (ESTPI) if one leg of three-level NPC inverter is failed. An optimal modulation algorithm of ESTPI is proposed in this paper. Due to the loss of one leg, the DC-link voltage utilization of ESTPI is reduced by half. Hence, an overmodulation algorithm...
Owing to the limitation of the switching losses and heat elimination, the maximum switching frequency of the high power motor drive system is generally lower. In addition, the fundamental voltage of the inverter can be effectively improved with overmodulation algorithm. However, the classical overmodulation algorithm for space vector pulse width modulation (SVPWM) needs to store a lot of data in advance...
