Investigation of inverters in multi-resonant mode with soft switching

This monograph presents the study of single-phase and three-phase inverters in the multiresonance mode with soft switching of transistors. When developing single-phase and three-phase inverters you must take into account not only the weight and size properties of the device the quality of the output parameters but also the modes of operation of transistors. The frequency of switching circuit keys and their maximum permissible power which determined in turn by their type plays an important role at high voltages and currents. The problem is aggravated by the fact that for each power circuit are used their modulation algorithms that depend on the load parameters. In some converters in addition to PWM characteristics it is necessary to choose a method of signal distribution between modules of different levels. The choice of solutions carried out by the designer based on personal experience which does not guarantee optimal circuit design. Thus the relevant issue is the study of single-phase and three-phase inverter operating in multi- resonant mode with soft switching mode of transistors which provide comfortable conditions for the transistors and the smallest losses.
