Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a DC/AC conversion system in which the voltage can be stabilized by adjusting an input DC voltage to a voltage suitable for output, loss is reduced effectively during conversion, use of a large capacity capacitor of one stage is omitted, and cost reduction and enhancement of conversion efficiency can be achieved.SOLUTION: A DC/AC conversion system for converting a DC input source into an AC output source comprises: a step-up module; a DC/AC conversion module; and a feedback module. The step-up module is a cross BOOST step-up circuit which receives the voltage of the DC input source and outputs a DC voltage required subsequently. The cross BOOST step-up circuit improves the DC voltage outputted by the step-up module by operating when the DC voltage cannot satisfy the requirement of the AC output source. The DC/AC conversion module receives a voltage outputted by the step-up module, and converts the received voltage to an AC output source. It is more practical.
