چکیده
This paper derives a family of digital non-linear waveform generators fundamental to the developement of an adaptive mixed-signal IC controller for power-factor-correction (PFC) of high-frequency switching AC-to-DC converters with the objective of significanlty lowering the cost of rectifier design. The controller application is described along with combined controller and power stage simulation results. Simple hardware implementations of digital waveform generators are derived and verified with experimental results from a 1 . 2 ~ CMOS test chip.

متن کاملLoad Frequency Control Based on Improved Fuzzy Controller in the Microgrid with Thermoelectric Generator
The Microgrid is a small-scale controlled power system, which can be used in islanded mode or in a grid-connected one to provide power. In the islanded Microgrid, the system frequency will be affected severely by the smallest disturbance which can happen due to light inertia in the system. In the independent Microgrid, several generation sources such as solar, wind, and so on can be considered....
