Modeling and analysis of zig-zag boost converter for battery charging applications

In a DC micro-grid (MG), the energy storage system (ESS) plays a vital role in doing the generation-load power management, DC bus voltage control and/or the power smoothening to provide a quality power to the load. In this paper, a new Bi-directional Boost converter topology denoted as Zig-Zag Boost converter (ZZB) is proposed as a charge controller for energy storage system for DC MG. The superiority of the ZZB over the conventional boost converter is that it can provide a comparatively higher gain with a better efficiency for the same duty cycle. Although this topology uses an extra switch and an additional inductor, the voltage and current stress of the switching and magnetic components is reduced, as well as the size of the inductors, resulting in lower overall cost and higher efficiency. Small deviations in the inductors and switches characteristics are perfectly acceptable, as the mismatch current is self-regulated to zero. This paper provides the complete model and an efficiency assessment of ZZB over other common topologies in the literature, while the results are validated via simulations in MATLAB/SIMULINK.

Abstract

In a DC micro-grid (MG), the energy storage system (ESS) plays a vital role in doing the generation-load power management, DC bus voltage control and/or the power smoothening to provide a quality power to the load. In this paper, a new Bi-directional Boost converter topology denoted as Zig-Zag Boost converter (ZZB) is proposed as a charge controller for energy storage system for DC MG. The superiority of the ZZB over the conventional boost converter is that it can provide a comparatively higher gain with a better efficiency for the same duty cycle. Although this topology uses an extra switch and an additional inductor, the voltage and current stress of the switching and magnetic components is reduced, as well as the size of the inductors, resulting in lower overall cost and higher efficiency. Small deviations in the inductors and switches characteristics are perfectly acceptable, as the mismatch current is self-regulated to zero. This paper provides the complete model and an efficiency assessment of ZZB over other common topologies in the literature, while the results are validated via simulations in MATLAB/SIMULINK.
