Abstract: Digital power supply controller is one of the key parts of SSRF high resolution high stability magnet power supply system. It is very essential to keep any degradation of these excellent properties by any stages as small as possible via careful testing when the controller is developed. In this study, a novel testing approach was presented, with which a novel closed control loop without actual power converter was constructed, and the new developed SSRF Digital Controller can work well in it.

Key words: SSRF, Digital power supply controller, PWM, Low pass filter
