Abstract
A non-isolated dc/ac converter for converting a dc input source into an ac output source is provided. The converter includes a dc/dc converting module and a dc/ac converting module. The dc/dc converting module includes a voltage shift circuit receiving an input voltage from the dc input source and outputting the input voltage, and a voltage boost circuit boosting an output voltage from the dc/dc converting module when the input voltage from the voltage shift circuit is insufficient for the ac output source. The dc/ac converting module receives the output voltage from the dc/dc converting module and converts the output voltage into the ac output source.
