Title: Apparatus and method for removal of variable offset component in current detecting signal
Inventor: YU HOZEN
IPC: H02P21/05
Filed: 2000-02-02
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method, for the removal of a variable offset component in a current detecting signal, in which the influence of an offset generated from a current detector can be removed. SOLUTION: A current detector 71 detects a three-phase current which is fed back from an AC motor and converts the three-phase current into a voltage detection signal which contains an offset component. A differential amplifier 72 differentially amplifies a fed-back analog offset signal and the voltage detection signal which contains the offset component. An analog/digital converter 74 converts the differentially amplified analog offset signal into a digital signal. A control part 75 finds a digital offset component on the basis of an offset instruction signal which is set by adding the converted digital signal, and it outputs a digital offset signal having a pulse-width modulation waveform after being proportional integration controlled.  A digital/analog converter 76 converts the digital offset signal which is output from the control part 75, and the analog offset signal is fed back to the differential amplifier 72.
