Abstract:
1. A high voltage deflection circuit for supplying a deflection current to a deflection coil, comprising: a first resonant circuit including said deflection coil that applies a first resonant pulse voltage to said deflection coil; a switching circuit connected to said first resonant circuit that performs a switching operation in response to a predetermined drive signal; a second resonant circuit, connected in series with said deflection coil and supplied with a drive voltage by a resonance operation of said first resonant circuit, that applies to said deflection coil a second resonant pulse voltage having an opposite polarity to that of said first resonant pulse voltage; and a third resonant circuit, connected in series with said first resonant circuit through said second resonant circuit, that performs a resonance operation in response to the switching operation of said switching circuit.
