    • A blocking oscillator contains a switching transistor which is driven by an integrated circuit. This circuit receives its supply voltage during the blocking phase from a winding at the primary side. A further winding at the primary side supplies the regulating variable for the integrated circuit during the flow phase. The supply input of the integrated circuit is connected by way of a further transistor and a diode to the control winding and a Zener diode biases the base of the further transistor. In the start-up phase in which the voltage of the supply winding (control winding) is built up, the circuit supplies the required operating voltage and switches off again in the steady state of the power unit.
    • 阻塞振荡器包含由集成电路驱动的开关晶体管。 该电路在阻挡阶段从初级侧的绕组接收其电源电压。 初级侧的另一个绕组在流动阶段提供集成电路的调节变量。 集成电路的电源输入通过另外的晶体管和二极管连接到控制绕组,并且齐纳二极管偏置另一个晶体管的基极。 在供电绕组(控制绕组)的电压建立的启动阶段,电路提供所需的工作电压,并在电源单元的稳定状态下再次关断。
