Title: Inverter controller
Inventor: OKAMURA MAKOTO
IPC: H02P27/06
Filed: 2003-02-10
Abstract: <P>PROBLEM TO BE SOLVED: To provide an inverter controller in which current distortion can be reduced even when the carrier frequency (carrier period) is switched.  <P>SOLUTION: A dead time control section 45 controls the occupancy of a dead time in the carrier period to a specified value or less before and after switching the carrier period and controls its variation rate to a substantially constant value (5% or less). Since the occupancy of a dead time is substantially constant even if the dead time is switched, the ratio of dead time in the carrier period is substantially invariant even if the carrier period is switched. Consequently, an abrupt change in occupancy of the dead time, an abrupt change in output current from an inverter and distortion of the waveform can be reduced greatly.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
