A PWM input control value F_OL_CTL generates a PWM output control signal to drive the converter to a selected output voltage. F_OL_CTL is added to each of a set of periodic, incrementally time-sequenced discrete frequency deviation control values F_DEV(t) having a periodicity of F_RESP corresponding to a frequency at which a response of the power stage is to be measured. A resulting set of perturbed PWM input control values F_CTL_PTB(t) frequency-modulate the PWM output control signal and perturb the converter output voltage. A corresponding set of perturbed converter output voltage samples V_OUT_PTB(t) is cross-correlated to the set of F_CTL_PTB(t) to generate correlation components of V_OUT_PTB(t) and F_CTL_PTB(t). Real and imaginary components of a frequency response of the converter power stage are determined from the correlation components for each F_RESP and together form the power stage transfer function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency controlled power converter characterization apparatus and methods","description":"A frequency-controlled power converter includes a power stage frequency response characterization circuit.
