Abstract (en)

[origin: WO2010004190A1] Quasi-resonant soft-switching inverter comprising: means (4, 6) for connection to an electrical power supply (8) having a DC voltage supply terminal (6) and a reference terminal (4); a first switching cell (301) and a second switching cell (302), of quasi-resonant type, which are connected in parallel between the supply terminal (6) and the reference terminal (4), characterized in that it further includes: a passive switching pole associated with a first switching cell (301); an active switching pole associated with the second switching cell (302); a device for controlling said switching cells (30), which delivers signals to a dual thyristor module with logic control; and a device (28) for controlling said active switching pole, said device being synchronized with said device for controlling the switching cells (30).
