腐蚀电源采用高频开关电源，效率高、用材少、输出纹波低、对电网影响小。 Corrosion power supply uses high-frequency switching power supply, with high efficiency, less materials, low output ripple, and small impact on the power grid. The main features of the HFP series high-frequency switching power supply we developed are soft switching, modular paralleling, autonomous current sharing and multi-characteristic output. The output of the unit module includes 500A, 1000A, 1500A, 2000A, 3000A and other series. The modularization of the whole machine can meet the needs of outputting thousands of amps to tens of thousands of amps.
The functional block diagram of the module and the waveforms of each segment are shown in the figure below. The inverter circuit composed of three-phase 380V city power rectification and filtering is added to the insulated gate bipolar transistor IGBT. The main circuit is converted into a high-frequency alternating current with adjustable pulse width (about 20KHz), and then the amorphous soft magnetic material is used as The high-frequency transformer of the iron core is stepped down, and the Schottky diode is rectified and converted into a low-voltage DC suitable for the working requirements. The control signal output by the control unit can respond quickly to the output of the main circuit, which not only gives excellent dynamic and static output characteristics, but also can compensate for various input voltage fluctuations, and can perform faults caused by various reasons. Quick protection response.
