  • Means and method for optimizing the switching performance of power amplifiers
    Patent number: 5107190
    Abstract: Reduced transient power dissipation and reduced variation of the transient power dissipation are obtained in high frequency power amplifiers, e.g., CRT horizontal deflection amplifiers, by sampling the amplifier output at and/or during the turning-off interval (e.g., during the storage time when transient power dissipation is still low and optionally also during turn-off when transient dissipation is large) and then, after a suitable delay, feeding back a signal proportional to the sampled output to the amplifier input driver to control the magnitude of the input drive during a subsequent amplifier-on interval. The desired delay corresponds approximately to the intervening amplifier-off interval.
