A new suboptimal pulse-width modulation technique for per-phase modulation and space vector modulation

Three-phase two-level inverters using space vector modulation (SVPWM) technology are one of the most popular inverter architectures today. The process of designing and manufacturing inverter systems usually goes through the following stages: simulation, hardware design, software programming on MCU, editing … In this article, we will focus on problem researching and implementing the SVPWM algorithm on an Arduino in detail. Besides, it is also based on the experimental survey of the inverter’s parameters, analyzing and proposing improved solutions for the inverter to operate optimally. SVPWM algorithm is tested on Arduino Mega 2560 board and small power inverter model.

In this paper, the effect of common-mode voltage generated in the three-level quasi-switched boost T-type inverter is minimized by applying the proposed space-vector modulation technique, which uses only medium vectors and zero vector to synthesize the reference vector. The switching sequence is selected smoothly for inserting the shoot-through state for the inverter branch. The shoot-through vector is added within the zero vector in order to not affect the active vectors as well as the output voltage. In addition, the shoot-through control signal of active switches of the impedance network is generated to ensure that its phase is shifted 90 degrees compared to shoot through the signal of the inverter leg, which provides an improvement in reducing the inductor current ripple and enhancing the voltage gain. The effectiveness of the proposed method is verified through simulation and experimental results. In addition, the superiority of the proposed scheme is demonstrated by comparing it to the conventional pulse-width modulation technique.

First of all, this paper speculates that the essence of the space vector pulse width modulation (SVPWM) is the injection of some kind of zero sequence component through the theoretical analysis. Increasing the range of output voltage and reducing the switching loss are the optimization it can realize, the essential realization method is implemented by changing the placement of zero space vector. Then the method is applied to the cascade multilevel carrier modulation. The main work of this paper is to analyze the relation between SVPWM and the carrier PWM in the two level converter, then add the discrete modulation into the cascade multilevel carrier modulation to verify that the space vector modulation can be realized in cascade multilevel and can get similar results with the two level.

This paper proposes a new regular sampled pulse width modulation (PWM) for three-phase current source inverters. The theoretical basis of the proposed modulation strategy is described, including dwell time calculations and switching sequence selection. This strategy is well suited for digital implementation, and enjoys all the flexibilities and degree of freedoms as in space vector modulation. In addition, it ensures a minimum number of switching transitions per fundamental cycle, unlike other PWM methods. It is therefore promising for high-power medium-voltage applications. The validity of the proposed modulation strategy has been confirmed using simulation and experimentation. To furthermore substantiate the superiority of the proposed modulation strategy against other PWM methods, its performance is compared to sinusoidal PWM, selective harmonic elimination, and space vector modulation.
