The use of switching regulator circuits at high power levels and high frequencies requires careful examination and control of the power dissipation during switching. In this paper it is shown a family of PWM soft-single-switched converters which, having only a single active switch, is able to operate with soft switching in a pulse width modulation way without voltage and high current stresses. In addition such converters can work at high switching frequencies for wide range of load. In order to illustrate the operating principle of these new converters a detailed study, including simulations and experimental test is carried out. The validity of these new converters is guaranteed by the obtained results.
