The primary winding is connected to a collector of one of the transistors Q1 and Q2, and through a capacitor, emitters of the transistors Q1 and Q2. The second winding is connected to bases of the transistors Q4 and Q5 and the emitters of the transistors Q4 and Q5. A maximum duty cycle of a pulse signal is determined according to a primary winding voltage of the transformer and a forward base-emitter voltage of the transistors Q4 and Q5.
