Improvement of the power conversion efficiency of a personal computer
2013 IEEE International Symposium on Industrial Electronics, 2013 Most low‐power PC design research focuses on the power consumption of devices in the system, in order to reduce the consumption of the peripheral components while the system is in the idle state. In this design, the power conversion efficiency of the multi‐phase pulse width modulation power regulator can be improved by using the auto‐phase switching ...
