Flyback transformer |
摘要 |
A flyback transformer which comprises: a primary-side coil; a secondary-side high-voltage coil divided into a predetermined number of coil pieces; high-voltage rectifier diodes connected, in the same polarity, in series with the coil pieces respectively so as to form a series circuit as a whole; a high-voltage capacitor connected to a cathode side of one of the high-voltage rectifier diodes located in a final stage of the series circuit; and an in-phase high-voltage coil reversely connected to the one high-voltage rectifier diode in the final stage of the series circuit so that a reverse pulse generated by the in-phase high-voltage coil is superimposed on the cathode side of the one high-voltage rectifier diode. Thus, an alternating electric field can be reduced without using any expensive externally-provided high-voltage capacitor which is insulated by an exterior housing and injection resin to thereby make it possible to provide a flyback transformer which is inexpensive in cost, which is high in reliability in view of insulation, and which is easy in handling.
