    Abstract: A system includes an inverter configured to output multiphase alternating current (AC) currents to an electric motor, the multiphase AC currents including a first phase current and a second phase current, the inverter including a set of switches for each phase current. The system also includes a switching controller operably connected to each set of switches, the switching controller configured to control a gate driver connected to a switch of the set of switches, the switching controller configured to determine a time difference between a first switching event of a first phase and a second switching event of a second phase during a switching cycle, and control a switching speed of the switch based on the time difference.

    Abstract: A method of distributing processor loading in a real-time operating system between a high frequency processing task and a lower frequency processing task, the method including: making a processing request to the high frequency processing task from the lower frequency processing task, the processing request including a plurality of discrete processing commands; queuing the plurality of discrete processing commands; and executing a subset of the queued processing commands with the execution of each of a plurality of high frequency processing tasks such that the execution of the plurality of discrete processing commands is distributed across the plurality of high frequency processing tasks.

    Abstract translation: 一种在高频处理任务和较低频率处理任务之间在实时操作系统中分配处理器负载的方法，所述方法包括：从较低频处理任务向处理请求提供高频处理任务，处理请求 包括多个离散处理命​​令; 排队多个离散处理命​​令; 以及执行排队的处理命令的子集，执行多个高频处理任务中的每一个，使得多个离散处理命​​令的执行分布在多个高频处理任务上。
