Abstract :
The state plane technique is used to develop a design-specification procedure that enables the designer to directly calculate the stresses on all elements of the different topologies for quasi-resonant power converters. If parasitic elements are considered, multiresonant topologies are obtained. These topologies can be calculated for the design specification if the procedure for quasi-resonant topologies is adapted to this situation. A novel theoretical approach for describing the internal behavior of multiresonant power converters and for visualizing the switching conditions and the points of maximum component stresses is proposed. The multiresonant switching technique combines two advantages: the lossless snubbing of both the transistor and the diode is achieved by only three reactive elements, and a controllable no-load operation is possible. This analysis procedure is well suited for calculating DC-DC power converter with an output power up to several hundred watts.<>
