N2 - Energy sources such as batteries, fuel cells, capacitors/ultracapacitors, solar cells etc., produce DC power. In many situations, it is required and advantageous to interface them to the main power grid. The DC voltage generated is stepped up and inverted to the appropriate voltage and frequency for grid integration by power electronic (PE) interface modules employing DC-DC converters and DC-AC inverters. The role of these PE systems are mainly three fold: 1) to invert the DC voltage into line frequency single/three-phase voltages, 2) to boost the low voltage DC into grid voltage, and 3) to provide electrical buffer between the energy source and the main grid lines. This paper presents an overview of two of the possible methods of inversion: a) DC-AC inversion with a DC-DC converter interface, b) single stage Z-source based DC-AC inversion. The two aforementioned systems are designed for a typical 1kW application. The circuit designs are verified with the aid of Saber Sketch simulation software. The first-cut design procedures presented in this work benefits the power supply designers by reducing the design time.
