PURPOSE:To attenuate harmonic voltage in the entire transformer by providing harmonic wave attenuating means at the position of the neutral point of alternating potential in the coil sections of high voltage coils divided in an alternating manner by a diode. CONSTITUTION:A transistor 12 is switched to flow harmonic current to a low voltage coil 11. A high voltage coil 13 is composed of two coil sections 15, 16 divided in an alternating manner by a diode 14. The low voltage terminal of the coil section 15 of low voltage side is grounded through harmonic wave attenuating means 17, and a high voltage terminal is connected to the anode of the diode 14. The coil section 16 is cut at the position of approximately half of the number of turns into two coil sections 16a, 16b, the low voltage end of the coil 16a is connected to the cathode of the diode 14, and the high voltage end is connected to the low voltage end of the coil section 16b through harmonic wave attenuating means 18. Rectified output is produced through a diode 19 from the high voltage end of the coil section 16b. |
