titleOfInvention Phase-locked loop (pll)-type resolver/converter method and apparatus
abstract An apparatus and method for determining an angle ψ an estimate of a true angle θ from a resolver excitation signal V ex (t)=A sin(ωt) and modulated resolver output signals V s (t,θ)=A×sin(θ)×sin(ωt) and V C (t,θ)=A×cos(θ)×sin(ωt), where ω is an angular frequency and t is time, is provided. The apparatus may include a converter comprising a closed loop phase-locked loop (PLL) system configured to produce an angle ψ and two digital signals BitØ(θ) and Bit 1 (θ) for estimating the true angle θ using V ex (t), V s (t,θ) and V C (t,θ) signals.
