<p>System intended to generate alternating current from direct current with a considerably high efficiency, the system being based on the use of complete bridges formed by four transistors with antiparallel diodes, and of which the novelty is the connection in series of two or more of such bridges so that the signals generated by each of the bridges are added together thereby obtaining a wave formed of multiple steps and which is very close to a perfect sine wave, and which is the desired wave in most applications. The system does not use any type of inductive element-based filter and enables to recover the reactive energy that the load may return to the system due to its reactive character. The system may be used in any type of installation but has been especially designed to be used in autonomous installations intended to generate energy from solar plates, wind generators, generating sets, or those which use the electric network.</p> |
