Multilevel Pulse width regulators based DC converters

The article analyzes the principles of construction and operation of multi-level bi-directional pulse-width controller DC-based capacitor DC-DC converters of the resonance type. Regulators have a low coefficient of harmonics of the input and output current, improved weight and size parameters and high efficiency. Effect is achieved using a Multicycle and tiered of operation, as well as soft-switching of transistor switches are part of the power circuit of the controller. The equations for calculating the parameters of the elements of the main circuit of the DCcontroller. The possibility of reducing the coefficient of harmonic currents consumed by the primary source.
