Resumen


El documento presenta de manera resumida, consideraciones para el diseño de un sistema de conversión DC-AC de 48 V dc a 120 V RMS, empleando una fuente elevadora con un puente H de inversión, presentando una regulación con base en un PI difuso con anti-windup. Adicionalmente se procede a la valoración bajo diferentes escenarios, sin regulación o en lazo abierto, con regulación o en lazo cerrado, con regulación ante variación de carga y luego ante variación de tensión de fuente. Finalmente se presenta la forma de valoración con base en estudios espectrales para análisis comparativos de manera gráfica y para establecer criterios de determinación del factor de rizo y THD o factor de distorsión armónica empleando estudios en frecuencia.


Palabras clave


Conversión DC-AC; Inversor; PI difuso; Anti-windup; Puente H; Regulación de tensión; Condiciones armónicas; Sistemas fotovoltaicos; Modulación PWM sinusoidal.
