<P>PROBLEM TO BE SOLVED: To provide an inverter circuit of a simplified structure capable of effectively reducing a variation in input current without using a large-capacity capacitor, and a photovoltaic generator. <P>SOLUTION: In a first mode, exciting energy is accumulated in a primary winding W1 by a current i<SB>1</SB>flowing from an input terminal, and the peak value of the current i<SB>1</SB>is controlled according to the command value of an inputting DC current. In a second mode, the exciting energy accumulated in the primary winding W1 is discharged to a capacitor C<SB>s</SB>, and further, the exciting energy is accumulated in the primary winding W1 by the discharge current i<SB>1</SB>flowing to the primary winding W1 from the capacitor C<SB>s</SB>. The peak value of the discharge current i<SB>1</SB>is controlled according to the command value of an outputting AC current. In a third mode, the exciting energy accumulated in a transformer TR is discharged to an output terminal via a switch SW1 or a switch SW2. <P>COPYRIGHT: (C)2004,JPO |
