Title: Controller of power converter and control method of power converter
Inventor: OGAWA RYUICHI
IPC: H02M7/48
Filed: 2019-08-13
Abstract: To suppress level skipping of a phase voltage and a line voltage in a controller of a power converter.SOLUTION: A controller of a power converter outputting a gate signal based on a table in which a pulse pattern preliminarily prepared is stored, and driving a switching element of the power converter determines whether or not level skipping occurs in the pulse pattern, and stores the pulse pattern without the level skipping in the table. In the determination of the level skipping, when a phase width of switching of the same phase and a phase width of switching between phases in the pulse pattern are larger than a threshold value θskip, it is determined that no level skipping occurs.SELECTED DRAWING: Figure 4
