“…The sampling period of the SVM was set to T C = 500 µs (2 kHz sampling frequency) in this research. The temporal resolution t r = 1 µs was chosen, as it was found to be the smallest practical amount of time in which twelve PWM outputs of TMS320F28379D DSC can be arbitrarily set and synchronized together [6]. As a result, every calculated switching time is rounded to 1 µs.…”

“…However, due to a lack of sufficient computing power of the microcontroller used in [5], only static states with a limited temporal resolution could be observed. The next step of the implementation was to overcome and compute the intensive nature of this kind of modulation method by using a dual-core TMS320F28379D digital signal controller (DSC), which was presented in [6].…”

The aim of this paper is to present the real-time implementation and measurements of a reduced switch count in space vector pulse width modulation for three-level neutral point clamped inverters (3L-NPC). We implement space vector pulse width modulation, which uses a prediction algorithm to reduce the number of switches in power transistors (switch count) by up to about 13%. The algorithm applies additional redundant voltage vectors. The method is compute-intensive and was implemented on a dual-core TMS320F28379D digital signal controller. The latest measurements of steady and dynamic states of electric drive, powered by a 3L-NPC inverter using this method, confirmed the possibility of using this method in practical implementation. The implementation and results of the measurements are presented in this paper.

This paper deals with the high performance of multi-level direct torque control (DTC) for induction machines without speed and stator flux sensors. The estimation is performed using a sliding mode observer, which is known for its robustness in high and low-speed operations, the control is based on a backstopping speed controller. This control technique was introduced years ago to circumvent the problems of sensitivity to parametric variations, it presents a high dynamic but their major problems are the variable switching frequency, the size and complexity of the switching tables, and undulations of the torque. The proposed approach is to replace switching tables with constant switching frequency control using three-level spatial vector modulation (SVM). Theoretical elements and simulation results are presented and discussed. As a result, the flux and torque ripple of three-level DTC-SVM control is greatly reduced compared to the flux and torque ripple of DTC-classic control. The advantages of the training system have been validated by the simulation results.
