Abstract

Minimizing the number of active switching devices in switched-mode power-electronic systems has a significant importance. Reduced complexity and switching losses, low cost, weight, and volume and high reliability are the main merits gained from implementing such reduced switch-count systems. To this end, this paper proposes a new three-phase dc-ac power converter topology for diversified applications based on Zeta dc-dc converter. The proposed power converter employs only four switches and naturally features a reduced-ripple sinusoidal output waveform with a peak line-voltage that could be extended to the full value of the dc-link input voltage. The integral sliding-mode control is employed to optimize the converter dynamics and ensure system robustness during different operating conditions. The proposed inverter topology is analyzed and its performance is validated using both simulations and experimentations.
