<p>PURPOSE:To stabilize a high output voltage without changing a horizontal deflection pulse voltage, by applying the output voltage of a resonance circuit composed of a saturable reactor and a condenser to the secondary circuit of a flyback transformer. CONSTITUTION:The resonance frequency of a resonance circuit constituted of a condenser 5 and a deflection frequency are set so as to coincide with each other when the inductance of a saturable reactor become minimum. Therefor, a DC output voltage obtained by rectifying a voltage at connection point between the reactor 4 and the condenser 5 by a diode 6, and smoothing the rectified voltage by the condenser 7 also becomes high. As the above output voltage is connected to the secondary coil 2 of a flyback transformer, a high output voltage increases and is stably controlled. Therefore, the high output voltage can be stabilized without changing a horizontal deflection pulse voltage.</p> |
