- H03K 4/501 the starting point of the flyback period being determined by the amplitude of the voltage across the capacitor, e.g. by a comparator
- H03K 4/52 using two semiconductor devices so coupled that the input of each one is derived from the output of the other, e.g. multivibrator
- H03K 4/54 using a single semiconductor device with positive feedback through a transformer, e.g. blocking oscillator
- H03K 4/56 using a semiconductor device with negative feedback through a capacitor, e.g. Miller integrator
