Abstract: This article shows a 12W single phase inverter modeling and its control design. From the switching model, we get the small signal model or lineal model with the aim to design a continuous time lead-lag compensator that is made discrete. The continuous and discrete answers are compared. The closed loop inverter simulation with continuous and discrete compensators and the answer of open loop inverter prototype are shown.

Keywords: Single phase inverter, Bode diagrams, Compensation, Transfer functions.

Resumen: El presente artículo ilustra el modelado y proceso del diseño de control, de un prototipo de inversor monofásico de 12W de potencia. A partir del modelo de conmutación se obtiene el modelo de pequeña señal o modelo lineal para diseñar un compensador de tiempo continuo en adelanto-atraso, el cual se discretiza para comparar la respuesta continua y discreta. Se presentan los resultados de la simulación del inversor en lazo cerrado con los compensadores continuo y discreto, así como la respuesta de la implementación del prototipo en lazo abierto.

Palabras clave: Inversor monofásico, Diagramas de bode, Compensación, Funciones de transferencia.
