  • Photovoltaic inverter
    Patent number: 10720880
    Abstract: A photovoltaic inverter includes a box, and an inverter cabinet, a direct current cabinet, an alternating current cabinet, a communication cabinet, and a power distribution cabinet which are all arranged in the box. The inverter cabinet is arranged on a first side of the box. The alternating current cabinet, the communication cabinet and the power distribution cabinet are all arranged on a second side of the box. The alternating current cabinet, the communication cabinet, and the power distribution cabinet are all arranged opposite to the inverter cabinet. The direct current cabinet is arranged on a third side of the box, and the direct current cabinet is arranged on a same side of the inverter cabinet and the alternating current cabinet.

  • Selecting a Precision Level for Executing a Workload in an Electronic Device
    Publication number: 20190310864
    Abstract: An electronic device includes a controller functional block and a computational functional block. During operation, while the computational functional block executes a test portion of a workload at at least one precision level, the controller functional block monitors a behavior of the computational functional block. Based on the behavior of the computational functional block while executing the test portion of the workload at the at least one precision level, the controller functional block selects a given precision level from among a set of two or more precision levels at which the computational functional block is to execute a remaining portion of the workload. The controller functional block then configures the computational block to execute the remaining portion of the workload at the given precision level.
