Which means connecting a 8mf capacitor, (plastic not electrolytic), or therabouts between the single phase live and the positive of the DC link. The effect is to double the Voltage at the DC link. But do not tell anyone I suggested this, and I will deny it........ Moderator may have a ‘fit’ here..... ........Cool or what.....
