Pulsation

Single-phase inverter pulsation

The inverter consists of power electronics components and is based on the principles of sinusoidal pulse width modulation (SPWM) to control a full-bridge circuit and an inductor–capacitor–inductor (LCL) filter. In this scheme the inverter is fed by a fixed input voltage and a controlled ac voltage is obtained by adjusting the on and the off periods of the inverter components. The advantages of the components. The single-phase inverter fabricated using low-cost components is designed and implemented to test on various AC loads, such as lamps, fans and chargers. In this study, the. . Abstract—A model predictive control-based second harmonic injection (MPC-SHI) method is proposed in this paper to attenu-ate the DC side second pulsation for the single-phase inverter.
