Publication number: 20090316458Abstract: The invention presents a structure for the conversion of direct current electric power into alternating current electric power, characterised in that it is simple, highly efficient and minimises the problem of electromagnetic compatibility. The circuit includes, in its first preferred embodiment, six switching elements governed by a command unit, four switches forming an H-bridge (T1, T2, T3, T4) and two auxiliary switches (T5D, T6D), and two auxiliary diodes (Daux1 and Daux2).
