Abstract: A power train may have a power train input and a power train output, wherein the power train is configured to transfer electrical energy from the power train input to a load coupled to the power train output in conformity with one or more power train control signals. A scheduler may be configured to receive events from the power train and, responsive to each particular event, schedule execution of a thread of control instructions responsive to the particular event, wherein the thread is selected from a plurality of threads. A processor may be configured to execute the threads of control instructions scheduled by the scheduler, such that for each particular event the processor generates one or more power train control signals responsive to the particular event within a first switching cycle of receipt of the particular event or within a second switching cycle immediately subsequent to the first switching cycle.
