Abstract:
1. A system comprising: an input selection module that selects a plurality of input signals from a power supply based on a first set of control signals, wherein the input signals include a duty cycle signal and a plurality of current and voltage signals of the power supply; a multiplier selection module that selects inputs from a sine generator and a cosine generator based on a second set of control signals; a multiplier module that selectively multiplies one or more of the selected input signals by one of the inputs from the sine generator and the cosine generator to generate products; an adding module that selectively adds the products to generate sums; a plurality of accumulators that accumulates the sums based on the second set of control signals; and an estimation module that generates the first and second sets of control signals and that estimates values of a plurality of components including an inductance, a capacitance, and a resistance in an output stage of the power supply based on the sums accumulated in the plurality of accumulators.
