Abstract
A class of single-phase quasi-switched boost inverter (qSBI) topology is developed for low power renewable energy source (RES) applications. This paper analyzes a three-phase embedded-type qSBI (E-qSBI) topology which is capable of boosting and inverting the available DC voltage in a single stage. The operating modes, steady-state analysis, and pulse width modulation (PWM) control of the boost inverter topology are discussed in detail in this work. The E-qSBI supplying, 100 W RL load is designed and simulated with MATLAB/Simulink software tool. The fast Fourier transform analysis (FFT) of output voltage waveform is carried out and the harmonic profile is presented. The simulation results are presented to show the effectiveness of single-stage embedded-type qSBI topology.
