A bi-directional scanning system for a CRT is disclosed comprising: a vertical CRT deflection coil, a horizontal CRT deflection coil; two class-E switchmode amplifiers which are connected in a push-pull arrangement to convert a positive DC voltage and a negative DC voltage to a generally sinusoidal current for operating the horizontal CRT deflection coil; and a staircase voltage generator for operating the vertical CRT deflection coil.
