PURPOSE:To reduce the driving power, by advancing the phase of output voltage waveform of the modulation waveform generator than the phase of deflection current. CONSTITUTION:Among the vertical deflection pulse V and horizontal deflection pulse H from the deflection circuit 2, the horizontal deflection pulse H is input to the waveform generator 6 via the phase lead circuit 5. The output of the waveform generator 6 is fed to the modulation waveform generator 10 and the adder 7. The output of the modulation waveform generator 10 is added with the output of the waveform generator 6 via the time sharing circuit 11. The added output is fed to the convergence circuit 9 after amplification. Thus, the delay and distortion of the corrected magnetic field having high frequency component required for the corner correction, can be satisfied with apparent lead time. Further, the separate winding 13 is provided to change the DC level. |
