[My 120 Watts Power Inverter]

hey i got the same circuit but i;ve encounter a different problem. first i bought the 74hc74, then when i tested the circuit , it does not work. i replaced it with the 74ls74 then it works. the problem is when i measured the ouput ac voltage it's over 400v. i only tested it with llights and then it works ,does the over voltage affects, i used a 12v motorcycle battery as dc source..
