摘要： A method and apparatus for correcting DC offset in a frequency to voltage converter. An analog frequency to voltage converter receives a frequency signal and outputs a voltage signal having a level that is indicative of the frequency of the frequency signal. The frequency signal is also input into a digital processor which converts the frequency signal into a reference signal that is fed back and summed with the voltage signal. The processor integrates the difference between the reference signal and the output signal to drive the output signal to be equal to the reference signal thereby nullifying DC offset in the output signal. The invention can be applied to controlling the DC bus voltage in a variable frequency AC drive.
