Improving the efficiency of power supplies with an adaptive control method
2013 10th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2013Normally power supplies provide a constant output voltage. A DC-DC converter in most of the applications is controlled by a voltage mode or a current mode controller. The DC converters are employed to feed electric vehicles, telephone sets and civil invertors, or for induction motors and frequency control.

Automatic Substrate Switching Circuit for On-Chip Adaptive Power-Supply System
IEEE Transactions on Circuits and Systems II: Express Briefs, 2006In energy-aggressive dynamic voltage scaling (DVS) techniques, adaptive on-chip power supply, which can provide variable voltage in a wide range, is highly demanded. However, potential leakage and latch-up problems arise, when substrate bias voltages of power transistors vary with the supply voltage.
