Conversión sigma-delta aplicada al control de inversores resonantes.

This paper presents an analysis of the sigma-delta conversion applied to the control of the DC link resonant inverters. This inverter configuration is often employed as a part of photovoltaic system because it presents the advantage that the semiconductors elements commute at zero tension or zero current. It happen on the high frequency elements and the inverter elements, and it is not necessary to modulate the DC tension, condition that simplified the control loop. Conversion analog-digital is an important step of the almost every modern electronics systems. After the signal is translated to the digital format, it can be processed easily in order to obtain the required information. [ABSTRACT FROM AUTHOR]
