Using constant current source as the excitation signal is an effective method for system testing of the aircraft. At present, the constant current source circuit built by TL431 voltage regulator does not meet the system test requirements of the aircraft under the condition of small current output. And when the temperature span is large, the working circuit does not have the ability to inhibit the...
Smart grids aim at evolving the traditional electrical grid system by making increasing use of sophisticated control and communication network technology, to properly deal with the high penetration of controllable assets, such as distributed generators and flexible loads, and their associated challenges. Since electrical grids are critical infrastructures, control strategies regulating their operation...
Electricity generation from renewable sources is increasing significantly, pushed by the need to meet sustainable energy goals in many countries. Control is a key enabling technology for the deployment of renewable energy systems in smart grids and to guarantee high-performance and reliable operation. To this purpose, a large variety of control strategies have been proposed or are still under investigation,...
Key blocks used for embedded <sc>nor</sc> Flash memory are introduced in this brief, including a novel sourceline (SL) voltage compensation circuit and a wordline (WL) voltage-generating system. The SL voltage compensation circuit controls the output voltage of the charge pump according to the number of cells to be programmed with data “0” to compensate the IR drop on the SL decoding path...
A method of dry resistance load test of diesel locomotive is introduced. The electric power generated by a dynamotor, which is driven by the diesel, is converted to DC and consumed on the dry resistances. As the heat dissipation of the resistances is about several thousand kilowatts, DC motor fans are used for air cooling the resistances. In order to save energy, the energy for driven the motor fans...
