Research on Repetitive Charging Control Technology for Parallel Operation of High-Power High-Frequency High-Voltage Charging Power Supply

With the development of pulsed power technology, the high voltage large current discharge pulse power supply needs more and more energy, which used for the high frequency repetitive discharging, so that the primary energy should be with high power and high accuracy. The High-frequency high-voltage capacitor charging power supply (CCPS) is widely used as the primary energy in the field of pulsed power because of its simple structure, mature technology and high stability, but restrict by the power density and charging speed, it has not widely used in the high frequency repetitive large current discharging. In order to enhance the out power, there are 15 CCPS are parallel connected at the output end, which are unified controlled by the upper computer software, so that the 15 CCPS can finish the rapid charging for the large capacitor load. At the same time, the voltage feedback and timing function of the upper computer software are used to control the repetitive charging frequency of the 15 CCPS, so that the charging precision and charging rate can be controlled accurately.
