Title:
INVERTER CONTROLLER
Document Type and Number:
Japanese Patent JP2017204913
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an inverter controller for driving upper and lower arm switches based on a pulse pattern, in which the NVH characteristics of an inverter can be improved.SOLUTION: A controller includes a pattern storage section storing multiple pulse patterns associated with at least the number of command synchronization, and a pattern generating section for generating a command pattern, i.e., the command value of switching pattern, based on a pulse pattern stored in the pattern storage section. The pattern generating section generates a command pattern based on the stored pulse pattern, so that harmonic content contained in the command pattern is switched to a different harmonic content with the passage of time, at the same number of command synchronization. With such an arrangement, spectrum of harmonic content is diffused.SELECTED DRAWING: Figure 5
