A Transformer Type High Voltage Power Supply with Insulated Ferrite Core

Abstract

The invention discloses an insulation ferrite core transformer type high voltage power supply, comprising an upper magnet yoke, a lower magnet yoke, primary magnet cores, secondary magnet cores and insulation layers; the four primary magnet cores are distributed between the upper magnet yoke and the lower magnet yoke; multilayer secondary magnet cores are installed on the magnet core posts corresponding to every primary magnet core; insulation layers are arranged between the upper and lower adjacent secondary magnet cores; the magnet yokes and the magnet cores are of ferrite material; a circuit structure comprises a primary coil circuit and a secondary coil circuit; the primary coil circuit comprises a primary coil, a square wave inverted circuit and a high frequency PWM rectifier; the high frequency PWM rectifier changes three-phase alternating current commercial power into the direct current; the square wave inverted circuit inverts the direct current into square waves as the input of the primary coil; the secondary coil circuit comprises a secondary coil and a full-bridge rectifying circuit; and the full-bridge rectifying circuit rectifies the square wave voltage sensed by the secondary coil into the direct current. The invention reduces the size of the high voltage power supply, greatly reduces the demand for rectifying capacitance and is continuous and stable in working state.
