In order to meet the requirements of comprehensive test of large current or large voltage for single heating circuit in China＇s large vacuum thermal test task, a rapid configuration system of programmable power supply for vacuum heat test is designed and constructed, which can solve the problems of the current complicated program-controlled power supply series parallel operation, the imbalance series- parallel power supply load serial and the outsanding security risks after series parallel implementation. Based on the existing vacuum thermal test control system architecture and program-controlled power supply model, the input and output electrical connector are designed accord- ing to the ratio of 2： 1. Using dual-IP dual power supply free combination of control output, the program-controlled power input and out- put status are detected through the microcontroller and relay control unit, the free power output configuration is achieved with the use of re- lay matrix, thus the serial and parallel quick configuration is realized for programmable power supply. The results show that, through the serial and parallel rapid configuration system of program-controlled power supply, the serial and parallel fast output of 15-way programmable power supply can be achieved within 3 minutes, which indicates that the current complex power supply string parallel operation is simplified, the program-controlled power supply string parallel operation efficiency is greatly improved, and the work of security is strengthened after the program-controlled power supply string in parallel.
