Abstract

A system includes an input selection module, a multiplier selection module, a multiplier module, an addition module, a plurality of accumulators, and an estimation module. The input selection module selects an input signal including a duty ratio signal and a plurality of current signals and voltage signals of the power supply. The multiplier selection block selects the inputs from the sine and cosine generators. The multiplier block multiplies the selected input signal by the inputs from the sine generator and cosine generator to produce a product. The addition module adds the products to produce a sum. A plurality of accumulators accumulates the sum. An estimation module estimates values ​​of a plurality of components including inductance, capacitance, and resistance of a power supply based on sums accumulated in a plurality of accumulators.
