Linear deflection amplifier with energy recovery.

摘要

Disclosed herein is a linear deflection amplifier which is suitable for processing horizontal sweep signals for driving a magnetic deflection yoke (22) of a radar CRT PPI (Plan Position Indicator) display. The amplifier features a transadmittance feedback where output current follows input voltage. Flyback resonance is derived by a shunt capacitor (18) coupled to an FET switch (20). Low cross-over distortion and temperature compensation of components within the system is achieved by use of a modified class B power mosfet push-pull configuration (Figure 1).
