Abstract
A system includes an input selection module, a multiplier selection module, a multiplier module, an adding module, a plurality of accumulators, and an estimation module. The input selection module selects input signals including a duty cycle signal and current and voltage signals of a power supply. The multiplier selection module selects inputs from sine and cosine generator. The multiplier module multiplies the selected input signals by the inputs from the sine and cosine generator to generate products. The adding module adds the products to generate sums. The plurality of accumulators accumulates the sums. The estimation module estimates values of a plurality of components including an inductance, a capacitance, and a resistance of the power supply based on the sums accumulated in the plurality of accumulators.
