schaltungsanordnung for correction of east westkissenverzerrungen.

摘要

1. A circuit arrangement for correcting pincushion distortion on the screen of a television receiver with a diode modulator (5), which is controlled via an input coupling coil (6) by a stage (8) switched by a line-frequency rectangular signal which is modulated at raster frequency, and with a diode (9) connected up to the input coupling coil (6) and serving to return stored energy into a supply voltage source of the television receiver, characterised in that an electronic switch (14) is connected in parallel with the diode (9), the rectangular signal being applied to the control electrode of switch (14), and the polarity of the contract-break is opposite to that of the diode (9), so that the switch (14) permits through the input coupling coil (6) a current which is oppositely directed to the diode current during the non-conductive phase of the connected stage (8).
