Abstract: A power supply system particularly adapted for use with an electrostatic precipitator to provide substantially ripple-free DC power for improved precipitator 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.

Abstract: A two-stage, high-voltage inductor assembly. The inductor assembly is particularly adapted for use in a power supply circuit for an electrostatic precipitator. The inductor assembly includes a first stage inductor member defined by a toroidal inductor member formed from a plurality of turns of wire to define an inductor member having a first inductance, and a second stage inductor member defined by a plurality of end-to-end ferrite elements carried on a copper conductor to define an inductor member having a second inductance. The first inductor member blocks the low to moderate frequency currents and voltages in the power output portion of an electrostatic precipitator power supply circuit, and the second inductor member blocks the intermediate and high frequency currents and voltages in such a circuit.

Abstract: A coaxial dye laser flashlamp, each electrode of which is made of spaced rings joined by several molybdenum strips evenly spaced about and between the coaxial quartz tubes of the flashlamp. The coaxial quartz tubes are then fused together in the regions of the molybdenum strips.
