Abstract
There is provided by this invention a dc power supply that utilizes capacitors in parallel with the diodes of the rectifier bridge in order to increase the full-power load impedance range of the power supply. In addition it has the capability to selectively couple the capacitors to the diodes over a predetermined frequency. This invention applies to both single phase and multiphase converters.
