Abstract
This paper aimed at presenting a topology for a two stage dc/ac inverter which is
suitable for grid connection of renewable energy sources. The main advantage of this
inverter is that it combines the operation of both CSI and VSI. Here no separate converter
is required for this inverter. Hence the efficiency of the whole system becomes high. The
main advantage is that only one power stage works at high frequency to achieve minimum
switching loss. The conventional Aalborg inverter is realized using a dual supply and
suitable for a range of 150V to 350V of input dc voltage. This range of voltage may not be
available from renewable energy source. Here single power supply is used in which input
voltage can vary from 40V. The evaluation of this topology is done through simulation
results.
