Abstract :
The evolution of the semiconductors in the field of the electronics of power pushes the originators more and more to design very compact converters of high frequency energy functioning, while having a very high energy efficiency. The objective of this paper is to improve the operation of a continuous alternating converter. This device consists of two stages of conversion ( DC / DC and DC / AC) ordered each one by a microcontroller (PIC). The discussed essential items are the Matlab simulation, the use of ISIS PROTUS for viewing control managed by two microcontrollers and finally the realization of the converter. The first stage of conversion (DC/ DC) is constructed by a boost chopper (24V/300V) powered by a photovoltaic generator and controlled by a PIC. This lift chopper feeds the second floor which is a converter bridge Mosfet transistors, each arm of the inverter is controlled by a driver of power which transmits order MLI of the PIC to Mosfet, the latter provides a square wave (50Hz, 230V).
