Abstract
Current-feedback magnetic multivibrators are widely used as power sources for electronic equipment, because they are highly efficient and are suitable for high-frequency operation. However, the oscillation frequency changes according to the load current, because it is determined by making use of the junction voltages of silicon pn junctions. We previously proposed an improved magnetic multivibrator with a frequency compensation circuit. In this paper, the conditions for the compensation are analyzed in detail. Since junction voltages are dependent on temperature, the analysis takes account of power dissipation in semiconductors.
