ABSTRACT:
A power supply method particularly adapted for use with an electrostatic particulate collection device to provide substantially ripple-free DC power for improved operation. The power supply is adapted to receive three-phase AC power and to transform the AC power into high voltage DC power having a minimum of voltage ripple in the output. The power supply includes a multi-phase transformer having three primary windings, each of the primary windings having associated with it a pair of secondary windings. The primary windings can be either delta connected or wye connected. One of each of the secondary windings associated with one of the respective primary windings are connected together in a delta connection arrangement, and the remaining secondary windings are connected in a wye connection arrangement. Because the respective AC voltage outputs of each of the secondary windings is out of phase with the AC voltage outputs of the other secondary windings, the resultant combined DC output voltage, after the DC voltages have been rectified in a three-phase full-wave bridge rectifier stack, produces minimum ripple voltage and current, without requiring additional, more expensive, and less reliable components.
