<p>A system (1) enabling common mode effects in high power inverter arrangements (12) to be compensated using relatively low power electronic components. A sensor (14) detects the common mode effects in leads (11) which connect the inverter (12) to an electric machine (13). This produces a compensation signal which is stepped up and coupled back into the leads by way of a transformer (15). Common mode voltages in the leads may be detected using a substantially resistive network.</p> |
