FPGA Techniques Based New Hybrid Modulation Strategies for Voltage Source Inverters

Abstract

This paper corroborates three different hybrid modulation strategies suitable for single-phase voltage source inverter. The proposed method is formulated using fundamental switching and carrier based pulse width modulation methods. The main tale of this proposed method is to optimize a specific performance criterion, such as minimization of the total harmonic distortion (THD), lower order harmonics, switching losses, and heat losses. The proposed method is articulated using fundamental switching and carrier based pulse width modulation methods. Thus, the harmonic pollution in the power system will be reduced and the power quality will be augmented with better harmonic profile for a target fundamental output voltage. The proposed modulation strategies are simulated in MATLAB r2010a and implemented in a Xilinx spartan 3E-500 FG 320 FPGA processor. The feasibility of these modulation strategies is authenticated through simulation and experimental results.

Self‐capacitor voltage balancing method for optimally hybrid modulated cascaded H‐bridge D‐STATCOM

“…One H-bridge is a PWM inverter, while the others are switched at low frequency for staircase wave generation. Another HM was based on the mixture of fundamental frequency and carrier based sinusoidal PWM, proposed for single H-bridge [27], and for two H-bridges [28].…”

Experimental and Numerical Investigations on Amalgamation of Mixed Frequency Carrier Based Asymmetrical 15 Level Multilevel Inverter

“…There are some gaps in the research crusade so far to investigate about the positioning the different high frequency carriers in the band of one cycle. This research explores the analysis of asymmetrical 15 is the obvious choice because of its parallel programming nature for generating the pulses for the switches [16]- [20]. Section II describes strategy of asymmetrical 15 level multilevel inverter and explains inventive digital PWM generation for the MLI.…”
