The penetration of distributed generation is increasing to assist main power plants worldwide. An efficient strategy of grid control integration, to interconnect the DG systems to conventional power systems, is required to improve the power quality and reliability (PQR). The main task of the interconnected system is to control and maintain frequency and voltage of the power system in an acceptable...
A three-phase intermediate frequency aviation inverter power with single chip microcomputer and SA8282 as its main controller is designed in this paper. The overall structure of the proposed system is given. The working principle and design method of the main circuit are presented in detail. Among the control circuit design process, the generation of SPWM waveforms, the main parameters design of SA8282,...
A high bandwidth critical path monitor (1 sample/ cycle at 4-5 GHz) capable of providing real-time timing margin information to a variable voltage/frequency scaling control loop is described. The critical path monitor tracks the critical path delay to within 1 FO2 inverter delay with a standard deviation less than 3 FO2 delays over process, voltage, temperature, and workload. The CPM is sensitive...
