STUDY OF CPWM MODULATION IN POWER ELECTRONICS CONVERTERS
Journal Title: Proceedings of Electrotechnical Institute Prace Instytutu Elektrotechniki - Year 2016, Vol 63, Issue 275
Abstract
In the paper, the research concerning the usage of the Chaotic Pulse Width Modulation (CPWM) in a buck step down converter was presented. The main purpose of the application of CPWM is the reduction of the EMI interference by flattening of the power spectrum of output voltage. This article contains the description of few types of the CPWM modulation. In all of them, a carrier signal behaves chaotically, what makes that the power electronics keys switch irregularly. A convolution with such a carrier signal makes that the power spectrum becomes fuzzier. The results of the presented study depicted on big possibilities of the CPWM modulation for the EMI interference reduction in power electronics, particularly in renewable energy devices.
