Abstract
The main ring magnet power supply for the KEK 12 GeV power supply consists of several 12-pulse thyristor rectifiers, DC filters, reactive power compensators, AC harmonic filters, and analog-digital control systems. Although a DC low-pass filter is effective for reducing the logical ripples over a few hundred hertz, lower-frequency uncharacteristic ripple components may be on the same order as or larger than logical ripples depending on the network condition. Some techniques for reducing these uncharacteristic ripple components are described
