<p><P>PROBLEM TO BE SOLVED: To provide a means which simply and surely detects the abnormality of a portable generator that is equipped with two or more power units each consisting of output winding and a rectifier circuit. <P>SOLUTION: This portable generator is equipped with two or more power units which have two or more pieces of output winding L1-L4 being wound independently of each other on the same iron core and rectifier circuits 2-5 being provided to corresponding to the output winding. The power units generate integrated output. Control means 33-35 control the rectifier circuits so as to conform the output voltage to the target voltage. A voltage deviation judging part 37 judges it to be abnormal in case that one of the output voltages of the rectifiers 2-5 and at least one of the rest are different from each other. A current deviation judging part 39 judges it to be abnormal in case that one of the output currents of the rectifier circuits 2-5 and at least one of the rest are greatly different from each other. When at least either the abnormality of the current or that of the voltage is detected, this stops the output of all the rectifier circuits 2-5. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
