Inverter apparatus for supplying a brushless DC motor with drive power |
| 摘要 |
<p>An inverter apparatus detects a common mode current (=I1) flowing from the phase windings (123r, 123s, 123t) of a brushless DC motor (120) to an earthing terminal (E) by way of the closed case (111) of a compressor (101), generates an electric current (I2) having a waveform similar to that of the detected common mode current (=I1) and forcibly offset the high frequency leak current (=I1) flowing from the compressor motor (120) by the generated electric current (I2). <IMAGE></p> |
