| Research Abstract |
The purpose of this study is to develop a variable-output magnetic oscillation inverter using a bridge-connected magnetic circuit. The target of output electric power of the inverter was set as 4 kW or more, and that of efficiency was set as 92 % or more.First, the magnetic core model of the bridge-connected magnetic circuit which can be used by a general-purpose electronic circuit simulator SPICE was devised, and then magnetic field distribution of inside, and outside, of the bridge-connected magnetic circuit was analyzed using three-dimensional magnetic field analysis software JMAG. Finally, maximum output electric power of 1.6 kW and power-conversion efficiency of 83 % were obtained in a trial magnetic oscillation inverter using bridge-connected magnetic circuit. These values, however, did not reach desired values.
