Title: Television receiver electric source
Inventor: PEETA EDOUARUTO HAFUAARU
IPC: H04N3/16
Filed: 1989-03-24
Abstract: PURPOSE: To reduce the amplitude and the duration time of ringing current in a high-voltage third order winding wire during a sweeping period by conducting a part of ringing current in place of an impedance through an attenu ator resistor and reducing the limit activation of ringing current, owing to the impedance during a certain period within a fly-back pulse period. CONSTITUTION: Ringing with large amplitude is generated in a voltage V3 which is generated between the both ends of damping resistor R2 as a ringing current attenuating means by ringing current I2 . In the latter half of a fly-back period, a diode D1 is reversely biased by current I2 and B+ applied voltage, so that the diode D1 is reversely biased during the latter half of the fly-back period and the sweeping period. Therefore, current I1 is permitted to flow mainly in damping resistor R2 which is serially connected to the winding wire W3 , so that the resistor R2 which consumes energy attenuates the ringing component of current I2 . Thus, the amplitude and the duration time of ringing current in the high-voltage third order winding wire are drastically reduced in the sweeping period, so that the latent adverse effects of current ringing is reduced.
