Re: [TCML] MMC pics



Really, series capacitors must be connected in a straight line, or with large clearances if there are turns. 10 kV will easily spark trough a 1 cm gap between points or sharp corners, or even more over a substrate that is not specially insulating. The single small resistors across the capacitors also probably don't have enough insulation and will fail. What I do is to assemble MMCs over an acrylic plate, using four resistors in series across each capacitor (in a zigzag pattern to save space), or group of capacitors in parallel. No more than tree capacitors in parallel for each bleeder, or a failure in a capacitor may be destructive, and not "heal" itself.
