A detailed analysis is presented of our original overloadprotected current-feedback magnetic multivibrator. Since current-feedback magnetic multivibrators are highly efficient and are suitable for high-frequency operation, they are widely used as power sources for electronic equipment. Unlike voltage-feedback magnetic multivibrators, however, their circuits have no ability to protect themselves from overloading. We therefore proposed a new current-feedback multivibrator with overload protection. In this paper, the conditions for cessation of oscillation are derived by using our model of bipolar junction transistors. This model takes account of power dissipation, because the commonemitter static forward current transfer ratio depends on the collector current and the junction temperature.
