| Abstract: | Objective To develop a high-quality high-voltage power supply device for the ion pump power supply so as to extend the service life of ion pumps. Methods Using a closed-loop controlled inverter circuit of U3842 Chip, a designed inverter frequency of 50 kHz was acquired, and after multiplying rectifier the acquired 7.5 kV DC high-voltage acted on the ion pump. Results Ideal DC high voltage pulse was acquired through circuit simulation analysis by the OrCAD Pspice software. Conclusion The design can meet the requirements of supplying power for ion-pump. |
