| Estonian abstract: | Leiutis kuulub jõuelektroonika ja jõupooljuhtmuundurite juhtimisvaldkonda ja käsitleb lühisolekute tekitamise meetodeid ühe- või mitmefaasilisele plokkjuhtimisega impedants-, kvaasiimpedants- ja transimpedants-tüüpi vaheldile. Vaheldit juhitakse kas pulsilaiusmodulatsiooni või faasinihkemodulatsiooni plokkjuhtimismeetodiga. Lühisolekute tekitamiseks plokkjuhtimise korral pakutakse välja kolm meetodit: lühisoleku tekitamine juhtivusolekute ülekatte teel, lühisoleku tekitamine vabavooluolekus ja lühisoleku tekitamine nulloleku sees. Lülituselementide koormuse tasakaalustamiseks PLM-meetodi korral kasutatakse juhtimismeetodit, kus vaheldi ülemiste ja alumiste juhtelementide juhtimissignaalid perioodiliselt vahetatakse. | |
| English abstract: | Invention is related to field of controlling of power electronics and power semiconductor converters and covers a method of shoot-through generation for impedance, quasi-impedance and trans-impedance inverters. The modified sine wave inverter can be controlled either by pulse width modulation or phase shift modulation method. Three methods are provided for generation of shoot-through states: generation of shoot-through by overlapping active states, generation of shoot-through during freewheeling states and generation of shoot-through during the zero states. To equalize the load in the case of pulse width modulation a control method is used where control signals of top and bottom side transistors are periodically swapped. | |
