Offset correction circuit of PWM inverter. |
| 摘要 |
<p>The DC offset in a current control system for a PWM inverter drive is corrected by integrating (11) a DC component of a current control signal (99) provided by a current control amplifier (9) and feedback controlling (12,97) the current control amplifier to reduce the DC component to zero.</p> |
