Abstract
Horizontal deflection circuits are disclosed which permit high-frequency operation through use of conductivity modulation MOS FET devices. Distortion of the horizontal deflection coil voltage is avoided by inclusion of compensation means utilizing an inductance to produce delay in the increase in magnitude of current flow during reverse recovery current flow. Use of a compensation means including an inductor and diode in parallel combination provides additional benefits of oscillation suppression.
