Research on the Control of Switch Power Supply Based on the Digital Potentiometers
Fu Yuan, Wang Lifang, Jun Liu · 2010
High frequency of the switch power supply requires high precision and speed of the control, which means high performance of traditional single-chip microcomputer (SCM). Based on the analysis to the switch power supply's control loop, a new control method by using digital potentiometers have been proposed in this paper, and its feasibility has been validated by experiment.
