Technology and design in electronic equipment| Summary: | The article presents the analysis of energy and magnetic processes in core of inductors switched-mode AC-AC and DC-DC converters. The mathematical model of energy and magnetic processes in core of inductors is obtained. The mathematical model is generalized to DC-DC and AC-AC converters, to most popular schemes of converters and to transfer, recuperation and idle modes. It is shown that the energy and magnetic processes in core of inductors are identical for DC-DC and AC-AC converters, for buck, boost, buck-boost and fly-back converters, and for transfer, recuperation and idle modes.It is shown that energy processes in converters can be defined by parameters of magnetic flux of inductor core. It is shown that power of converter will be maximal, when value of ripple induction in core is equal the maximum allowable induction of core, and average value of induction in core is equal half of the maximum allowable induction of core. It is shown that maximum power of converter is proportional volume of inductor core. |
