This paper presents the results of EMI reduction techniques applied to power electronic converters. The techniques applied included shielding control and power signals, separating power system references regarding reference for instrumentation and measurement signals, implementing analog filters and configuring an appropriate switch trigger system for electronic power to decrease shifting EMI emissions to the maximum. This paper presents the results before and after applying the techniques to reduce interference. The results were also verified by using two real time control strategies rapid control prototyping (RCP).
En este artículo se presentan los resultados de la aplicación de algunas técnicas de reducción de EMI en convertidores electrónicos de potencia. Las técnicas aplicadas incluyen el apantallamiento de señales de control y de potencia, la separación de las referencias del sistema de potencia de las señales y medidas, la implementación de filtros análogos y la configuración de un adecuado sistema de disparo, de tal forma que se disminuyan al máximo las emisiones tipo IEM. En este artículo se presentan los resultados obtenidos antes y después de aplicar las técnicas de reducción de interferencias. Además, los resultados son verificados usando dos técnicas de control en tiempo real RCP (Rapid Control Prototyping).
