Self-excited intermittent oscillator basic circuit

Self-excited intermittent oscillators are commonly used as power amplification, waveform transformation and pulse signal sources. Its circuit is shown in the figure. It
is an amplification circuit that implements positive feedback through a transformer, and the base loop is connected to an RbCb timing circuit .
    Oscillation period Tt. +tk, where tq is the rest period width and ￡k is the pulse width. Generally, tk <￡q, so T≈
￡k =RbCbln(l+l/ju), where is the transformation ratio of the transformer T, generally 楷 ÷ 1～5. Capacitance Cb affects both pulse
width and pulse period. In the figure, VD is the clamping diode.
