Abstract

DC60 (20/12/42) The step-up coil of a high-voltage transformer for powering a cathode ray tube consists of coils packed in chamber (79) of the coil forming body (72). These coils are made in pairs (55, 56). The inner end (57) of the first coil of the pair is connected to the terminals (58,60) of the first diode (59), the inner end (61) of the second coil of the pair is connected to the terminals (62,64) of the second diode, or vice versa, the outer end (75) of the first coil (51) of the pair (55,56) is connected to the terminals (58,60) of the first diode (59), the outer end (65) of the second coil of the pair is connected to the terminals (62,64) of the second diode (63). Thus, the capacitance between the coils of the pair is not activated. The consequence of this is a reduction in the residual oscillations of the output voltage. The step-up coil of a high-voltage transformer for powering cathode ray tubes consists of coils housed in chamber (79) of a coil forming body (72). These coils are made in pairs (55,56). The inner end (57) of the first coil of the pair is connected to the terminals (58,60) of the first diode (59), the inner end (61) of the second coil of the pair is connected to the terminals (62,64) of the second diode, or vice versa, the outer end (75) of the first coil (51) of the pair (55,56) is connected to the terminals (58,56) of the first diode (59), the outer end (65) of the second coil of the pair is connected to the terminals (62,64) of the second diode (63). Thus, the capacitance between the coils of the pair is not activated, the consequence of which is a reduction in the residual oscillation of the output voltage.
