<P>PROBLEM TO BE SOLVED: To provide a line filter that copes with regenerative current, capable of preventing destruction of a switching element ASG used for regenerative function. <P>SOLUTION: The line filter, corresponding to the regenerative current, has a circuit change-over switch which prevents the destruction of the switching element for the regenerative function with the timing of release of the function for returning the regenerative current to an input power source, for the purpose of preventing the DC power source of an inverter driver from being boosted, in deceleration driving of a motor. <P>COPYRIGHT: (C)2007,JPO&INPIT |
