This paper presents a control scheme for a three-phase grid-connected photovoltaic (PV) system operating in a grid connection and isolated grid mode. Control techniques include voltage and current control of grid-connected PV inverters. In the grid-connected mode, the grid controls the amplitude and frequency of the output voltage of the PV inverter. The inverter operates in the current control mode...
This paper reports on the first low power (10.4 mW) and ultrasensitive linear Hall-effect integrated circuits (LHEICs) using GaAs–InGaAs–AlGaAs 2D electron gas technology. These LHEICs have a state-of-the-art sensitivity of $533~\mu $ V/$\mu $ T and are capable of detecting magnetic fields as low as 177 nT (in a 10-Hz bandwidth), at frequencies from 500 Hz to 200 kHz. This provides at least an order...
Through the research on modeling and SOC estimation of the battery in the isolated Micro-grid, the behavior characteristics of the battery was analyzed under normal and stable operation, and further more, the condition was determined to guarantee the stability of system based on SOC of the battery. Under the premise of stable operation, a control strategy was put forward based on SOC to adjust the...
In recent years, thermal management, which improves the reliability, performance, power leakage, etc. of modern microprocessors, has been the subject of numerous computer architecture and system software studies. To determine the detailed thermal distribution of a microprocessor is among the critical tasks for thermal management. However, because thermal modeling tools require considerable computation...
