Abstract

With the rapid development of electromagnetic launch technology, the performance requirements for the charging power supply are increasing. To control the charging rate accurately and get the steady load voltage, a phase-shift control system was designed. This system adopted the control method which regulates the phase angles of the driving pulses by calculating the relationship of the voltage feedback and the preset charging time. According to the topology and application requirements of high-voltage high-frequency charging power supply (HVHFCPS), the simulation platform based on the PSIM software was set up. A prototype of HVHFCPS based on voltage feedback and phase-shift control was developed. The experimental results shown that the load voltage can be controlled accurately.
