【発明の名称】偏向巻線に偏向電流を発生させる装置
Document Type and Number:
Japanese Patent JP2544720
Kind Code:
B2
Abstract:
An apparatus for generating a periodic resonant pulse voltage across an inductance (LH1,LH2) includes first (Q1) and second (02) switches coupled together in a series cascode arrangement. The cascode arrangement applies a first voltage to the inductance for storing energy therein. A periodic switching signal is coupled to the second switch (Q2). Each cycle of the switching signal includes a turn-on portion and a turn-off portion. The initiation of the turn-off portion makes the second switch (02) nonconductive to enable the inductance (LH1,LH2) and a resonating capacitance (Cr) to form a resonant circuit that generates a resonant pulse voltage at a terminal (41) of the resonant circuit. A damper switch (D1) is coupled to the inductance (LH1,LH2) for terminating the generation of the resonant pulse voltage at the end of the first interval, prior to the initiation of the turn-on portion of the switching signal. The voltage at the resonant circuit terminal (41) is coupled to the control electrode (base) of the first switch (Q1) for supplying current thereto during conduction of the damper switch (D1). This enables the first. switch (Q1) to conduct current from the inductance (LH1,LH2) during conduction of the second switch (02).
