An active power filter implemented with multiples single-phase full bridge voltage-source inverters connected in series (known as cascaded hybrid asymmetric multilevel inverter or binary multilevel VSI) is presented and analyzed in this paper. The proposed active power filter is aimed to compensate current harmonic components in medium and high voltage power distribution systems. A control sche...

ABSTRACT—The Z-Source Inverter (ZSI) overcomes the disadvantages of the traditional Voltage-Source Inverter (VSI) and Current-Source Inverter (CSI).It can buck and boost its output voltage by utilizing the shoot-through state which is forbidden in traditional VSI. Different Pulse Width Modulation (PWM) techniques are available for the control of Z-Source Inverters. In the traditional PWM techni...

This paper presents multicarrier PWM strategies for three phase cascaded seven level Z-source inverter. Multilevel inverters posses the advantage of reduced harmonics, high-power capability and high-voltage level. Impedance network in the cascaded multilevel inverter circuit will perform boost operation. This paper focuses on multicarrier sinusoidal pulse width modulation (MCSPWM) strategy for ...

This paper presents a deadbeat-based proportional-integral (PI) controller for a stand-alone single-phase voltage source inverter using a battery cell as the primary energy source. The inverter system is simulated in MATLAB/Simulink. It consists of a lead acid battery, third-order Butterworth low-pass DC filter and AC filter, H-bridge inverter, step-up transformer, and a variety of loads, as we...

In this paper, a new family of single-stage high step-up boost voltage inverter based on transformer is proposed, called T-Z source inverters. By replacing two inductors in the classical Z-source inverter with two transformer, the proposed inverter produces a very high boost voltage gain when, the turn ratio of the transformer is larger than one. Compared to the trans-Z source inverter, the pro...
