A hysteresis space vector modulation for interleaved Vienna rectifier fed 3‐level neutral point clamped inverter system

Abstract

Summary In this article, a hysteresis space vector modulation (HSVM) is developed for interleaved Vienna rectifier (IVR) fed 3‐level neutral point clamped inverter (NPCI) system. The minimized current ripple and improved output voltage is obtained using HSVM control technique. The output of IVR is fed with 3‐level NPCI, which provides continuous input source, balanced capacitor voltage and minimized common mode voltage. Hysteresis circular region‐based control method is implemented to minimize the current ripple in the rectifier side. The multicarrier sinusoidal pulse width modulation technique is used to control 3‐level NPC inverter, which provides reduced total harmonic distortion (THD), balanced capacitor voltage and improved output voltage. This proposed system outputs are verified using MATLAB simulink and FPGA processor for simulation and experimental results, respectively.

Design of 15 level reduced switches inverter topology using multicarrier sinusoidal pulse width modulation

“…Abundant modulation strategies were urbanized to organize converter power switches [13]. In that, the converter with high frequency pulse width modulation (PWM) methods like carrier based modulation, trapezoidal method, sinusoidal PWM, space vector modulation and multicarrier based PWM used [14], [15]. Moreover, selective and active harmonic exclusion nearest vector control method and synchronous optimal PWM are used for converter with low frequency PWM techniques [16], [17].…”
