Title:
METHOD AND DEVICE FOR REGULATING PULSE IN MULTI-LEVEL CONVERTER, AND MULTI-LEVEL CONVERTER
Document Type and Number:
WIPO Patent Application WO/2017/016485
Kind Code:
A1
Abstract:
A method and device for regulating the pulse in a multi-level converter, and the multi-level converter, wherein, the method includes the steps: determining the voltage difference between the positive bus and the negative bus according to the voltage of the positive bus and the voltage of the negative bus (S402); determining whether the voltage difference between the positive bus and the negative bus exceeds the preset threshold value (S404); under the condition that the voltage difference between the positive bus and the negative bus exceeds the preset threshold value, according to the positive and negative state of the voltage difference between the positive bus and the negative bus, overlapping the preset pulse width trimming quantity to each phase pulse width, so as to regulate the output pulse width (S406). With the method, the limit of choosing vector can be canceled.
