and the total harmonic distortion of the output current is less than 5%. These results satisfy a required condition for interlinking a power converter to a utility line in Japan [16], [17]. The input dc current and voltage are maintained constant, and the resultant power pulsation caused by single-phase power generation appears on the decoupling capacitor voltage, Vx . The maximum conversion efficiency of the proposed inverter is only 70%. This is because that the rated input dc voltage is set to very low, 35 V, and hence the power loss on the power MOSFET devices becomes large. This imperfect result should be improved by using devices exhibiting high performance and low conduction loss. Also, revising the modulation method will give us a useful solution.
