Implementation of Switching Algorithm for SVPWM Inverter in Induction Motor Drive System on Electric Vehicle Applications

Abstract

Electric cars are the way to reduce global warming and fuel shortages. Performance variable speed drive is needed for various drive electric vehicle applications. Unfortunately, high performance is still being investigated with a variety of drive systems. This paper presents a design, analysis, and implementation of the SV-PWM inverter motor drive system. The SV-PWM algorithm in design using Matlab, to analyze the system include signal response, THD-V, THD-I. All algorithms are embedded in STM32F4, as the main controller. The hardware uses a 3-phase motor control Steval power module. Response speed and output signal inverters are shown in chart form for analysis

Development and Performance Evaluation of Integrated Hybrid Power Module for Three-Phase Servo Motor Applications

“…In order to improve its computational complexity and inefficiency, a simpler and more computationally effective SVPWM scheme has been developed through injecting a triangular zero-sequence signal to the sinusoidal waveforms (SPWM) to create non-sinusoidal modulation waveforms. This approach is also known as zero-sequence injection PWM [ 41 ]. The non-sinusoidal modulation waveforms would possess a lower peak voltage than SPWM, and more importantly, the modulation index can be further maximized, so that the output voltage can reach the limit of the DC bus voltage.…”

“…The non-sinusoidal modulation waveforms would possess a lower peak voltage than SPWM, and more importantly, the modulation index can be further maximized, so that the output voltage can reach the limit of the DC bus voltage. According to the literature report [ 41 ], the maximum linear modulation index is 1.15. The calculation principle is depicted as follows, assuming that there is a virtual neutral point o in the DC link voltage (as shown in Figure 9 a), the voltages of phase U and phase V relative to point o can be represented as: where V no is the phase voltage difference between the neutral point n and the virtual neutral point o .…”
