Self-excited converter circuit
专利汇可以提供Self-excited converter circuit专利检索，专利查询，专利分析的服务。并且PURPOSE:To protect a transistor for control, and to insure stable action of a self-oscillation of self-excited converter circuit by a method wherein a diode is connected between a base and an emitter of the transistor for control. CONSTITUTION:At the self-oscillation of the self-excited converter circuit, when a reverse voltage to the resonance voltage is generated in the tertiary winding N3, the diode 18 is in conducting condition to the reverse pulse voltage, accordingly the reverse pulse voltage generated from the tertiary winding N3 is applied to the base of a switching transistor 2 through a resistor 9 for bias and the diode 18 to insure ON, OFF action of the switching transistor 2. Moreover at this time, because the diode 18 is in conducting condition to the voltage between the base and the emitter of the transistor 8 for control, the transistor 8 for control is held at a voltage less than VBEO to be protected.，下面是Self-excited converter circuit专利的具体信息内容。
