Enhanced Predictive Torque Control for Three-Level NPC Inverter-Fed PMSM Drives Based on Optimal Voltage Magnitude Control Method

IEEE transactions on power electronics, 2023
The major drawback of conventional predictive torque control (PTC) is that it fixes the magnitude of the reference voltage vector (VV) to 70%. This limitation results in large torque and flux ripples and slow dynamic response, especially when the ...

Cascaded impedance networks for NPC inverter

2010 Conference Proceedings IPEC, 2010
Multilevel inverters are getting more and more attracted because they have better output waveform quality and lower semiconductor voltage stress. The Z-source NPC is a kind of single stage multilevel inverter which has the ability of voltage boost. But the boost capability is relatively low when they are subject to the renewable sources. To date, three

Thirteen level cascaded NPC inverter

2010 IEEE 26-th Convention of Electrical and Electronics Engineers in Israel, 2010
The paper presents a novel, thirteen level, and cascaded, neutral point clamped inverter. The inverter is modulated by phase disposition (PD) carrier based PWM method. The load of the inverter is a synchronous machine. The simulation results for different voltage levels, different modulation frequencies, and different carrier frequencies are presented.

A 30kW transformer-less PV NPC inverter

2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012
Conventional PV power converters are usually based on configurations that include DC-DC boost converter stage, voltage source inverter stage, passive filter stage and grid interface isolation transformer, whose presence implies less efficiency and higher costs, in particular for medium size power PV converters.

Single phase ZVS PWM NPC inverter

XI Brazilian Power Electronics Conference, 2011
This paper presents a zero-voltage, pulse width modulated, NPC inverter, with active voltage clamping using only two auxiliary switches. The structure is particularly simple and robust. It is very attractive for high-power applications, single or multiple phases, due to neutral point accessible at the NPC topology.
