Abstract

Compared to conventional technologies based on low-frequency thyristor-controlled power-supply units, the high-frequency power-supply units of electrostatic precipitators, based on a new cutting-edge technology, ensure more efficient gas conditioning at thermal power plants and industrial enterprises. Particular attention in the design of high-frequency power-supply units should be paid to designing a step-up transformer with high nominal output voltage and capacity at an operational frequency from several to tens of kilohertz. The design features of this transformer significantly influence the characteristics of the whole high-frequency power-supply unit. This article proposes an approach to forming a broadband design transformer model which correctly works in a broad range of low and high frequencies. This model allows imitating processes in the transformer together with an external circuit; in this case, it is possible to analyze the influence of the transformer design on the characteristics of the whole unit, as well as the operating conditions of the transformer itself, which is especially important in the device design phase.
