Description
Technical field
The utility model relates to power supply technique application, especially relates to a kind of high-frequency and high-voltage power supply subpackage rectifying device.
Background technology
Transformer is one of parts of electric cleaner key.The common rectifier structure that current electric precipitation Switch Power Transformer adopts.Common rectifier structure uses extensively, uses problem little to low-frequency power (50HZ), but for the rising of high-frequency and high-voltage power supply due to operating frequency and operating voltage, the parasitic capacitance of line bag and the effect of parasitic capacitance of rectifier bridge just very important.In high-frequency and high-voltage power supply, the rectifier diode parasitic capacitance (junction capacitance of diode and body parasitic capacitance) of coil parasitic capacitance and rectifier bridge to power-efficient and reliability effect very large.Coil parasitic capacitance directly causes conversion efficiency to reduce.The parasitic capacitance of diode causes diode unbalanced-voltage-division even, makes high-side diode dividing potential drop exceed rated voltage (in voltage transient change procedure) and damage.Above factor causes the reduction of power conversion performance.
Utility model content
The utility model, in order to overcome the deficiencies in the prior art, provides a kind of high-frequency and high-voltage power supply subpackage rectifying device.
To achieve these goals, the utility model is by the following technical solutions: a kind of high-frequency and high-voltage power supply subpackage rectifying device, comprise high frequency transformer and high-voltage rectifier, described high frequency transformer comprises primary coil and secondary coil, this secondary coil is at least two independently line packages, each line package connects a high-voltage rectifier, and this high-voltage rectifier is connected mutually formation output.Line package is set, realize subpackage rectification and reduce the voltage often organizing high-voltage rectifier, the even property of unbalanced-voltage-division that transient voltage produces because of the parasitic capacitance of diode can be reduced, improve the reliability of high-voltage rectifier, ensure stability in use, and avoid damaging because of overtension; Subpackage rectification is because the buffer action of high-voltage rectifier, and the alternating voltage of each line package, no longer to the parasitic capacitance generation effect of other line packages, reduces the impact between line package; Enhance the anti-interference of power supply, improve power conversion performance.
Further, described high-voltage rectifier comprises two diode circuits parallel with one another and electric capacity electricity.Structure is simple, and result of use is good.
Further, described high-voltage rectifier comprises rectification circuit and fixed head, and fixed head is provided with some louvres.Enhance the heat dispersion of rectification circuit.
In sum, the utility model improves the conversion efficiency of power supply, strengthens stability and the antijamming capability of power supply use.
