Overload-Protected Frequency-Compensated Current-Fed Multivibrator

Current-feedback magnetic multivibrators are widely used as power sources for electronic equipment, because they are highly efficient and reliable. However, these circuits have no ability to protect themselves from overloading, and the oscillation frequency changes according to the load current. In this paper, we propose a new current-feed-back multivibrator with overload protection and frequency compensation. In addition, the condition for cessation of oscillation and that for fixed frequency of oscillation are derived by analysis. These conditions can be determined independently of each other.
