Zusammenfassung:The invention relates to a static converter meant to convert electricity from direct current into alternating current, where the direct current supply source exhibits voltage variations and permits energy recovery. According to the invention, the static converter comprises a voltage inverter with a reduced number of fully controllable semiconductor devices, assisted by anti-parallel diodes (Tand Tor T, T, Tand T), power supplied from a direct current (V) by means of some passive components LC (L, L, C, C, C) and a controllable semiconductor with an anti-parallel diode (T). Invenţia se referă la un convertor static, destinat conversiei energiei electrice din curent continuu în curent alternativ, în condiţiile în care sursa de alimentare de curent continuu prezintă variaţii ale tensiunii şi permite recuperarea energiei electrice. Convertorul static, conform invenţiei, este alcătuit dintr-un invertor de tensiune cu un număr redus de dispozitive semiconductoare complet comandabile, asistate de diode în antiparalel (Tşi Tsau T, T, Tşi T), alimentat de la o sursă de curent continuu (V), prin intermediul unor componente pasive LC (L, L, C, C, C), şi un semiconductor comandabil, cu o diodă în antiparalel (T).
