PROCEDIMIENTO PARA LA CONVERSION DE UNA TENSION CONTINUA PROCEDENTE DE UNA FUENTE DE TENSION CONTINUA, EN ESPECIAL UNA FUENTE DE TENSION CONTINUA FOTOVOLTAICA, EN UNA TENSION ALTERNA.

摘要

An alternating current (AC) voltage circuit is decoupled from a direct current (DC) voltage circuit during free-wheeling phases using switching elements (V1-V4) arranged in the direct current voltage circuit, so that free-wheeling current flows through one of free-wheeling diodes (D1-D4) in decoupled state. Independent claims are also included for the following: (1) circuit arrangement for converting direct current voltage to alternating current voltage; and (2) inverter.
