<P>PROBLEM TO BE SOLVED: To overcome the problem in a device of an inverter control for determining a conduction width and controlling an output and for processing a workpiece at each timing of an inverter control, wherein a magnetization of a transformer occurs when a sudden change occurs for the conduction width of an inverter drive, and an excessive current is energized in a switching element of a first side, resulting in damaging the switching element of the first side. <P>SOLUTION: A method of inverter control is provided for preventing a switching element of a first side from being damaged, by monitoring a motion of a conduction width of a next period which the conduction width is suddenly changed, and by limiting the conduction width to prevent the occurrence of magnetization. <P>COPYRIGHT: (C)2011,JPO&INPIT |
