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. The first and second inductor members can be carried on a single body member which can be of tubular construction and in which the first inductor member is exteriorly carried on the body member while the second inductor member, which is electrically connected with the first inductor member, is interiorly carried within the tubular body member.
