Abstract :
The paper deals with the analysis of DC/AC converter with non - usual topology of output LC filter. This new topology allows operate without dead-times applied on switching transistors therefore output voltage distortion caused by this protection times is significantly reduced. This topology is especially determined for converters with new very fast transistors (SiC, MOSFET) operating with high PWM frequency where volume and weight of the LC filter doesn´t bring any problem with space and price.
