Abstract: Deflection apparatus for a raster scanned cathode ray tube display
comprises a flyback circuit (T2,T4,Ly,Df,Cf) including a switch (T2,T4)
connected in series with an inductor (Ly). The switch (T4) is responsive
to a line drive signal (LINE) to alternately open and close a current
path through the inductor (Ly) between a first voltage level (B+) and a
second voltage level (OV) lower than the first voltage level (B+) to
generate a raster scan current signal in a deflection coil of the
display. The amplitude of the raster scan signal is determined as a
function of the first voltage level (B+) and the frequency of the line
drive signal (LINE). A feedback circuit (D2,R3,D3,C2) connected to the
switch (T4) generates a feedback signal (F) as a function of current
flowing out of the switch (T4). A regulator (600-630,T3,L,D1,C1) is
connected to the flyback circuit (T2,T4,Ly,Df,Cf) for varying the first
voltage level (B+) as a function of the feedback signal (F) to maintain a
