Dual current controller of inverter interfaced renewable energy sources for accurate phase selection method and grid codes compliance
A method for correct operation of the current-angle-based phase-selection method (PSM) is based on a proper dual current controller (DCC) for inverter interfaced sources during unbalanced fault conditions. The fault type is determined in the inverter using voltage-angle-based PSM. Accordingly, fault-type zones' bisectors of the current-angle-based are determined. Consequently, an initial negative-sequence current angle reference is determined to force the relative angle between the negative- and zero-sequence currents in the center of its correct fault-type zone. The initial positive-sequence current angle is determined according to reactive current requirements by grid codes. These initial angles are updated for accurate operation of the PSM and appropriate reactive current injection. Negative- and positive-sequence current references are determined in the stationary frame to comply with the reference angles and inverter's thermal limits. These references are regulated by a proportional-resonance controller. |

Dynamically boosting read voltage for a memory device
Systems, methods, and apparatus related to dynamically determining read voltages used in memory devices. In one approach, a memory device has a memory array including memory cells. One or more resistors are formed as part of the memory array. A memory controller increments a counter as write operations are performed on the memory cells. When the counter reaches a limit, a write operation is performed on the resistors. The write operation applies voltages to the resistors similarly as applied to the memory cells over time during normal operation. When performing a read operation, a current is applied to one or more of the resistors to determine a boost voltage. When reading the memory cells, a read voltage is adjusted based on the boost voltage. The memory cells are read using the adjusted read voltage. |
