摘要:
The present invention relates, without being limited thereto, to the field of power electronics and non-linear control, and in particular to a topology structure of a multilevel power converter of the type of a cascaded bridge. The present invention provides a new configuration of power converter comprising a functional block and is composed of a low number of devices; five sources of DC voltage, nine semiconductor switches, and two semiconductor diodes. Where switches S1, S1 and S2, S2 are devices complementary to each other. On the other hand, switch S3 corresponds to a bidirectional switch. The present invention, in addition, presents a plurality of functional blocks connected in series, each of said functional blocks having the configuration of the circuit.

摘要:
Process for producing a biofertilizer, comprising the following steps: a) solid-state fermentation to produce enzymes and nutrients critical for plant nutrition; b) immobilization through allophane nanoparticles of the enzymes and substrates produced during stage a); and c) a second fermentation to favor the development of microorganisms that improve the quality of the biofertilizer. Protection is also sought for the biofertilizer that is produced from this process.
